Question

How Variable valve change

Answer 1

Share your code so we can check the error.

Answer 2

You didn't return x. So the value of x is not changed. Do the following changes:

public static void main (String [] args)
{
int x=5,y;
y=square (x);
System.out.print(y);
}
int square ( int x)
{
int y=x*x;
return y;
}

Answer 3

public static void main (String [] args)
{
int x=5;
Square (x);
System.out.print(x);
}
Static void square ( int x)
{
Int x=x*x;
}
