How to fix "error: class found on application class path: Main" in java for visual studio code

this is my first time posting here and would like how to solve this error message. It appears only sometimes and only lets me build on a program called Main.java. I'm a begginer programmer so please bear with me, this is the code im trying to run:
import java.util.Scanner;
import java.text.NumberFormat;
public class Main {
public static void main(String[] args) {
Scanner priceScanner = new Scanner(System.in);
System.out.print("Price: ");
int price = priceScanner.nextInt();
Scanner interestScanner = new Scanner(System.in);
System.out.print("Interest rate: ");
double interest = interestScanner.nextDouble();
Scanner numberOfPaymentsScanner = new Scanner(System.in);
System.out.print("Number of payments: ");
int numberOfPayments = numberOfPaymentsScanner.nextInt();
Double monthlyInterest = interest / 1200;
Double result = ((double)price * ((interest * Math.pow((1 +
interest), (double)numberOfPayments))/((Math.pow((1 + interest),
(double)numberOfPayments)) - 1)));
NumberFormat currency = NumberFormat.getCurrencyInstance();
String mortgage = currency.format(result);
System.out.println("Your mortgage is: " + mortgage);
}
}
I haven't seen any comprehensible ways to solve this problem online, and the only thing i think could solve it is to reinstall java in another drive and change the classpath.
Thanks for your attention.

I solved it - my mistake. While executing the program using the terminal I was typing java Main.java, whereas the correct execution method was to type java Main.

With Single-file source-code programs which is a new way of executing 1 File Java programs is only available since Java 11. You can run the command:
java (Java File Name without .java extension)
java Main.java
Though please take into consideration that this way of executing only works if your Java project is only 1 Java File.
FYI:
This single-file source code will be executed fully in memory and you can only import code that came with the JDK you are working.
Finally if you want your code to run as fast as possible compile with javac before executing you program.
javac Main.java
java Main
Just be careful that there is no Main.class already in the folder, this may cause a confusion to the compiler.

Step 1:
javac + Filename.java
Step 2:
java + Filename // execute without add .java

Java user console input on sublime text 3 not working

I am trying to get the user to enter their name and have it be printed out on java using Sublime Text 3. After the user enters their name when a message prompts them for it, their name is supposed to be printed out but it justs skips over to a new blank line. It works on online compilers but not on Sublime. How do I get user console input to work on Java Sublime Text 3?
import java.util.Scanner;
public class SocSecProcessor {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter name: ");
String name = input.nextLine();
input.close();
System.out.println(name);
}
}

You have to launch execution in a separate console, not the sublime text pseudo console.
The solution is to launch with START command in a batch file .bat
for example:
START CMD /K %RELATIVE_PATH%\jdk\bin\java -cp %~dp1 %~n1
where %1 is the file class with main method. Go to the batch syntax documentation if necessary... Your build system in sublime must launch a batch file with this kind of
instruction.

How to make input ( Scanner ) work on Sublime Text 3 when using JAVA?

I just started learning JAVA and Sublime Text 3 was proposed to me as a great compiler for JAVA code. I downloaded it, started programming and set my build system as JavaC. I wanted to create a quick program adding two numbers given by the user and displaying the result but nothing comes up in the "build" section. Do you have any idea to make that work ?
Here is the code I wanna try:
import java.util.Scanner;
public class Example
{
public static void main(String[] args)
{
int a,b;
Scanner input=new Scanner(System.in);
System.out.println("Enter a number:");
a=input.nextInt();
System.out.println("Enter a number:");
b=input.nextInt();
System.out.println("sum=" + (a+b));
}
}

For future references on how this windows command line or command prompt in windows works.
First check if your computer have the JRE (required to run a Java program) and JDK ( required compile and run Java programs) already install to verify this input the text "java -version" and javac -version into the Command Line. If the Javac is already intalls, however, doesn't show in the command line then you need to follow this sites on how to set up the path depending on your OS.

Cannot find the scanner

I have a very bad experienced about the scanner because I am using GUI and JOptionPane. So I am not be able to do the program's interns of scanner because. I am new to it so Please help me, "cannot find the scanner". This is my code so far .
import java.io.*;
import java.util.*;
class MultiplicationTables{
public static void main(String args[]){
int n, c;
System.out.println("Enter an integer to print its multiplication table");
Scanner in = new Scanner(System.in);
n = in.nextInt();
System.out.println("Multiplication table of "+n+" is :-");
for ( c = 1 ; c <= 10 ; c++ )
System.out.println(n+"*"+c+" = "+(n*c));
}
}

If your Java is not version 1.5 or above, Scanner class is not provided.
go to command promt
type "java -version"
check your version.If you have outdated just update. Problem shoud be fixed..
and make sure your IDE or the JDK actually use it.
Code that you have here provided is correct so you can use it after you fix your problem.

First import is redundant.
import java.io.*; // you can remove it
Scanner is a class in java.util package.
Check weather you have properly set your jdk path in your ide, or in your system.
Depends on system that you use:
Windows: Advanced System Settings->Environment Variables->Path check weather there is your path to jdk.
UNIX in console print 'echo $PATCH' and check that if you have there jdk path properly added.
And then you can check your version of java independent to system in console writing
java --version

Executable Jar files

How can I get this Java code to run outside of Eclipse?
import java.util.*;
public class Calculations {
public static void main(String[] args) {
Scanner console = new Scanner (System.in);
System.out.println("So... you want to figure out what the Hypotenuse of any Right Triangle is but your to");
System.out.println("lazy to do it your self huh..Sigh... Ok well, At least your being honest about it :)");
System.out.println();
System.out.println("Lets do this...Pythagoreom Style");
System.out.println();
System.out.println("First things first, whats your Sine? And no I don't mean if your an Aquarious or");
System.out.print("some shit like that, I mean your Y value or the first side of your triangle? ");
double side1 = console.nextDouble();
System.out.println();
System.out.println("Okayyyy and now as any good math teacher would say, Whats your Cosine or X value?");
System.out.print("(You might as well learn some Trigonometry while your taking the easy way out) ");
double side2 = console.nextDouble();
System.out.println();
System.out.println("Ok give me a minute... ");
System.out.println();
System.out.println();
System.out.print("Oh, by the way whats your favorite food? ");
String x = console.next();
System.out.println();
System.out.println();
double hypotonuse = Math.sqrt((Math.pow(side1,2)+ Math.pow(side2,2)));
System.out.println("So you favorite food is " + x + " Huh...well...THATS BESIDES THE POINT!!! BACK TO MATH!!!");
System.out.println();
double sum = (Math.pow(side1,2)+Math.pow(side2,2));
System.out.println("So if your First Side is "+side1 + " and we square that and your Second Side is " + side2+ " and we square that too,");
System.out.println();
System.out.println("we can add those sides together to get our sum of "+sum+" Finally we can square root "+sum+ " and Viola!");
System.out.println();
System.out.println("Pythagoras says your Hypotenuse is "+ hypotonuse);
System.out.println();
System.out.println();
System.out.println("HHHAAAZZZAAAAA!!!! FOR MATH!!! HAAAZZZAAAA for Pythagoreum!!!");
System.out.println();
System.out.println();
System.out.println("Oh, and P.S.");
System.out.println();
System.out.println("I'm just kidding, I care about your favorite food,");
System.out.println();
System.out.println("Here's a pyramid type thing of it built by a ratio given by your Hypotenuse :)");
System.out.println();
System.out.println();
for( int i =1; i <=hypotonuse; i++)
{
for (int w = 1; w<=(hypotonuse-i); w++)
{
System.out.print(" ");
}
for(int v=1; v<= (2*i-1); v++)
{
System.out.print(" "+ x );
}
System.out.println();
}
}
}

In Eclipse go to File>Export>java>Runnable jar file>Launch conf pick main class. export dest. destination of file after exporting >finish
after that you can run jar for example with command line(so you can see your console) type cmd in search and run jar by going into your directory where jar is located ..Command for running jar file java -jar nameofjar.jar

Though you can export the class from Eclipse and run it, I would recommend doing it from first principles to understand the process. Later after you understand the basics and work on complex applications, you can use a build tool like ant or maven to generate the jar file and run it.
First principles way:
Ensure you can run java compiler and JVM from command line. You should add your JAVA_HOME/bin to PATH for that to work.
Open command prompt. cd to the directory where you have the Calculations.java file.
Compile the java code by issuing command javac Calculations.java
Compiler generates Calculations.class file in the directory.
You run the compiled class outside Eclipse by issuing command java Calculations. Yes, you don't use .class extension in the command.
If you have multiple class files in a bigger project you can package them into a jar file using command jar -cvf calculations.jar *
It generates calculations.jar file which contains compiled code.
You run the code inside the jar by issuing command java -jar calculations.jar Calculations

Have written this from memory, as I don't have access to eclipse right now.
Right click the project
Export
Executable/Runnable jar file.
(these next 2 steps may be in the wrong order)
Make sure you select the correct class for the main method.
Select the file location and file name
Click done/finish
Browse to your jar, run it

You could always run it from command line

It is answered here and here on stackoverflow with a great detail.
Also you are attempting to run a 'console' applicaiton from jar (which normally doesn't show anything if you execute the jar). You can follow these instructions about how to do it.
Also, though not related to Eclipse IDE, but if you want to experiment netbeans IDE this process is much easy there (Run --> Clean and Build Project) or Shift + F11 automatically creates an executable jar file for the project, located under dist directory.
