public static void main(String[] args) {

// TODO Auto-generated method stub

int[] iray ={1,2,3,4};

char[] cray ={'b','u','c','y'};

printMe(iray);

System.out.println();

printMe(cray);

}

public static void printMe(int[] a)

{

for(int x: a)

System.out.printf("%s", a);

}

public static void printMe(char[] a)

{

for(char x: a)

System.out.printf("%s", a);

}

}

This returns output as :

[I@15db9742[I@15db9742[I@15db9742[I@15db9742

[C@6d06d69c[C@6d06d69c[C@6d06d69c[C@6d06d69c

Why is the answer returning address values. However, when I replace a in print statement with x initialized in advance for loop, it returns correct value ie

1234

bucy

Why is that so?
