public class sample
{
public void displayValue (int a, int b)
{
System.out.println("a = "+a +" b = "+b);
}

public int displayValue (int a, int b)
{
System.out.println("a+b:"+(a+b));
return (a+b);
}

public static void main(String[] args)
{
sample t = new sample();
t.displayValue(10,10);
int x = t.displayValue(20,30);
}
}



Output:

D:\Prg>javac sample.java
sample.java:8: displayValue(int,int) is already defined in

^
sample.java:18: incompatible types
