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
public int displayValue (int a, int b)
^
sample.java:18: incompatible types
found : void
required: int
int x = t.displayValue(20,30);

You cannot traverse through Black cells. 3. There should be only one Red and Green cell and at least one of each should be present. Otherwise the array is invalid. 4. You cannot revisit a cell that you have already traversed. 5. The maze need not be in the same as given in the above example
