Question

Consider the following Java methods.


int func2(int w) {

return w * 3;

}

int func1 (int a, int b) {

int n = a + b;

return 2 + func2(n);

}

int start() {

int z = 4;

return func1(z, 1) - 3;

}

What is the return value of the call start()?

​

Answer 1

Answer:

14

Explanation:

func1(4, 1) -3;      [ =>func1(4,1)=2+func2(n); n=4+1]  

2+ func2(5) - 3;    [   => func2(5) = 5*3 =15  ]

2 + 15 - 3
