Java code, passing parameter to method

i sing

I am not sure what I am doing wrong here, here is my code

package methods;

public class example {
    public static int sum(int x, int y){ 
        return x+y; 
    }
    public static void printSomething() {
        int a = 1; 
        int b = 2; 
        System.out.println("The sum of "+ x + " and "+ y +" is "+sum(a,b)); 
    }
    public static void main(String[] args) {
        System.out.println("Hello"); 
        printSomething();
    }
}

I want to print the sum of x and y is 3

Oscar Lopez

Try this:

System.out.println("The sum of "+ a + " and "+ b +" is "+sum(a,b));

The parameter name xsum yis local to the method definition and is called sum in the current scope .ab

Alternatively, and for coherence reasons, you can simply rename aand buse the xand method. The result will be exactly the same, but now the variable will have the same name.yprintSomething()
