I have list values in stream while iterating I need to check if that value is negative or not if negative return zero or else retrun same value
Below is my code
{
Inventory .stream().
map.(inventory.value).sum;
}
You can just use Math.min for this. You'll have to map over them as integers, presumably:
Inventory.stream()
.mapToInt(it -> Math.min(0, it.value))
.sum()

for (Pair p : pairs) {
double f = foo(p)
...
}
foo() performs a simple mathematical calculation as follows:
double foo(Pair p) {
return Math.cos(p.x) + Math.sin(p.y);
}
If all the items in pairs are the same, can the Java compiler optimise this using Common subexpression elimination? Or is there another optimisation that occurs? I am asking since I have found a significant time reduction when more values in pairs are the same.

I am trying to code an algorithm to implement Gamma Correction but I am unable todo so with below code, because of a high power base. Wondering if anyone could fix below code to raise color values between 0,1 Thanks
The problem is in your math.
int / int will cause a truncation.
If red = 9 and you execute 9 / 255 the result is 0.
Try making all your literal values floating point
(for example 255.0 instead of 255).

For example, I have my main method as well as the method returnOdds(original), that returns the integer array "odd"
How would I print the elements of this array in the main method? With a for loop?
A for loop would work. If you don't care about the format, though, a simpler solution might be to use Arrays.toString, which will convert in the form "[elem1, elem2, ..., elemn]".
"With a for loop?"
answer : "yes"

String[] arraylist = {"0","0","0","0","0","0","0"};
but now I want to replace inside the array above to 1, to make it like this
String[] arraylist = {"0","0","0","1","0","0","0"};
Once try follow if you know position you want to change
arraylist[3]="1";
Hope this will helps you.

Still getting the red bar. What's wrong with the AssertEquals?
public void testFindEmployeeByID() {
StubEmployeeRepositoryImpl result = new StubEmployeeRepositoryImpl(dataSource);
List<Employee> emp = result.findEmployeesByName("John", "X");
assertEquals("John"+"X", result.findEmployeesByName("John", "X"));
}
Probably assertEquals doesn't know how to compare List and String...
