Answer 1

Prabhjot Singh You need to write return statement outside loop.

Also use return statement in loop when condition will satisfy otherwise program will stop there and next iteration will not work and you will never get actual result.

public static String sevenBoom(int[] numarr){
for(int i:numarr){
if (i == 7) {
return "no 7 in array";
}
}

return "Boom!";
}

Edited - I just provided solution here. Don't compare with original code.

Martin Taylor To give solutions I don't think we need to write same code as given in problem. Anyway we don't need to discuss on this.

Answer 3

Martin Taylor I know. I just gave solution. Don't think that is Wrong. I intensely changed value.

Answer 4

Martin Taylor Now I have changed. Now it will return "no 7 in array"? I thought people have sense here.
