String in Java can we convert "Hello" into Hello

Hello all I an new to java I just want to know that can we convert "Hello" in Hello. I have gone through the internet answers but found that if any string has "" in that so we can use the replace method of java. So I just want to convert the "Hello" into Hello. So if you know please help
suppose
String s="Hello"
//Required Operation
System.out.println(s);//It should print Hello.
So if you know please help me. Actually I have a file which contains lots of data having " " and I only want that data without double quotes so is it possible to convert that.

Here is an example:
String s = "\"hello\"";
String result = s.replaceAll("\"", "");
System.out.println(result);
Actually if you declare your string String s="Hello", the variable s will not contain any quotes, because the quotes are Java syntax and mark the start and end of the String.

Use String.replaceAll()
str = str.replaceAll("\"", "");

As all the other answers you're able to use:
str = str.replaceAll("\"", "");
But their is another solution if you just want to erase the 1st and last char of your string ( so your " here) is to use substring like:
str = "Hello";
str = str.substring(0,str.length()-2);
I think that it could work for you

How to replace substrings that contain any integer in java?

How to replace a sub-string in java of form " :[number]: "
example:
string="Hello:6:World"
After replacement,
HelloWorld

ss="hello:909:world";
do as below:
String value = ss.replaceAll("[:]*[0-9]*[:]*","");

You can use a regex to define your desired pattern
String pattern = "(:\d+:)";
string EXAMPLE_TEST = ':12:'
System.out.println(EXAMPLE_TEST.replaceAll(pattern, "text to replace with"));
should work depending on what exactly you want to replace...

Do like this
String s = ":6:";
s = s.replaceAll(":", "");

Edit 1: After the question was changed, one should use
:\d+:
and within Java
:\\d+:
This is the answer for replacing :: as well.
This is the regexp you should use:
:\d*:
Debuggex Demo
And here is a running JavaCode snipped:
String str = "Hello :4: World";
String s = str.replaceAll(":\\d*:","");
System.out.println(s);
One problem with replaceAll is often, that the corrected String is returned. The string object from which replaceAll was called is not modified.

Splitting string into substring in Java

I have one string and I want to split it into substring in Java, originally the string is like this
Node( <http://www.mooney.net/geo#wisconsin> )
Now I want to split it into substring by (#), and this is my code for doing it
String[] split = row.split("#");
String word = split[1].trim().substring(0, (split[1].length() -1));
Now this code is working but it gives me
"wisconsin>"
the last work what I want is just the work "wisconsin" without ">" this sign, if someone have an idea please help me, thanks in advance.

Java1.7 DOC for String class
Actually it gives you output as "wisconsin> " (include space)
Make subString() as
String word = split[1].trim().substring(0, (split[1].length()-3));
Then you will get output as
wisconsin
Tutorials Point String subString() method reference

Consider
String split[] = row.split("#|<|>");
which delivers a String array like this,
{"http://www.mooney.net/geo", "wisconsin"}
Get the last element, at index split.length()-1.

String string = "Enter parts here";
String[] parts = string.split("-");
String part1 = parts[0];
String part2 = parts[1];

you can just split like you did before once more (with > instead of #) and use the element [0] istead of [1]

You can just use replace like.
word.replace(char oldChar, char newChar)
Hope that helps

You can use Java String Class's subString() method.

How to get specific string out of long string

I have the following String (it is variable, but classpath is always the same):
C:.Users.mho.Desktop.Eclipse.workspace.GIT.BLUBB...bin.de.test.class.mho.communication.InterfaceXmlHandler
and I want to get just
de.test.class.mho.communication.InterfaceXmlHandler
out of this string. The end
InterfaceXmlHandler
is variable, also the beginning before 'de' and the path itself is variable too, but
de.test.class.mho.
isn't variable.

Why not just use
String result = str.substring(str.lastIndexOf("de.test.class.mho."));

Instead of splitting you could get rid of the beginning of the string:
String input = "C:.Users.mho.Desktop.Eclipse.workspace.GIT.BLUBB...bin.de.test.class.mho.communication.InterfaceXmlHandler";
String output = input.replaceAll(".*(de\\.test\\.class\\.mho.*)", "$1");

You can create a string-array with String.split("de.test.class.mho."). The Array will contain two Strings, the second String will be what you want.
String longString = ""; //whatever
String[] urlArr = longString.split("de.test.class.mho.");
String result;
if(urlArr.length > 1) {
result = "de.test.class.mho." urlArr[1]; //de.test.class.mho.whatever.whatever.whatever
}

You can use replaceAll() to "extract" the part you want:
String part = str.replaceAll(".*(?=de\\.test\\.class\\.mho\\.)", "");
This uses a look-ahead to find all characters before the target, and replace them with a blank (ie delete them).
You could quite reasonably ignore escaping the dots for brevity:
String part = str.replaceAll(".*(?=de.test.class.mho.)", "");
I doubt it would give a different result.

Android - how to replace part of a string by another string?

I have strings with some numbers and english words and I need to translate them to my mother tongue by finding them and replacing them by locallized version of this word. Do you know how to easily achieve replacing words in a string?
Thanks
Edit:
I have tried (part of a string "to" should be replaced by "xyz"):
string.replace("to", "xyz")
But it is not working...

It is working, but it wont modify the caller object, but returning a new String.
So you just need to assign it to a new String variable, or to itself:
string = string.replace("to", "xyz");
or
String newString = string.replace("to", "xyz");
API Docs
public String replace (CharSequence target, CharSequence replacement)
Since: API Level 1
Copies this string replacing
occurrences of the specified target
sequence with another sequence. The
string is processed from the beginning
to the end.
Parameters
target the sequence to replace.
replacement the replacement
sequence.
Returns the resulting string.
Throws NullPointerException if target or replacement is null.

MAY BE INTERESTING TO YOU:
In java, string objects are immutable. Immutable simply means unmodifiable or unchangeable.
Once string object is created its data or state can't be changed but a new string object is created.

In kotlin there is no replaceAll, so I created this loop to replace repeated values ​​in a string or any variable.
var someValue = "https://www.google.com.br/"
while (someValue.contains(".")) {
someValue = someValue.replace(".", "")
}
Log.d("newValue :", someValue)
// in that case the stitches have been removed
//https://wwwgooglecombr/

String str = "to";
str.replace("to", "xyz");
Just try it :)

I noticed that you commented in 2011 but i thought i should post this answer anyway, in case anyone needs to "replace the original string" and runs into this answer ..
Im using a EditText as an example
// GIVE TARGET TEXT BOX A NAME
EditText textbox = (EditText) findViewById(R.id.your_textboxID);
// STRING TO REPLACE
String oldText = "hello"
String newText = "Hi";
String textBoxText = textbox.getText().toString();
// REPLACE STRINGS WITH RETURNED STRINGS
String returnedString = textBoxText.replace( oldText, newText );
// USE RETURNED STRINGS TO REPLACE NEW STRING INSIDE TEXTBOX
textbox.setText(returnedString);
This is untested, but it's just an example of using the returned string to replace the original layouts string with setText() !
Obviously this example requires that you have a EditText with the ID set to your_textboxID

You're doing only one mistake.
use replaceAll() function over there.
e.g.
String str = "Hi";
String str1 = "hello";
str.replaceAll( str, str1 );
