Resolving “The method must return a result of type int” in Java

Question

I\'m very new to Java. Eclipse is giving me the error

The method must return a result of type int

for the following code:

Answer 1

For your second error, the logic seems to be off a little... there is no return statement in the case where b > a.

Answer 2

This Eclipse error has already been answered by other users. Anyway here is an alternative to find the largest number of type int

Alternative - Find the largest integer, using stream():

public static int largest(int a, int b, int c) {
    return Arrays.asList(a, b, c).stream().max(Integer::compareTo).get().intValue();
}

Summary of the error:

Here is the Eclipse error:

The method must return a result of type int

Reson for error:

Not all condition are taken care of in method largest. "Outside" condition 'if(a > b)' a "return an int" is needed.

Alernative - 'if statements' using Clean code's concept 'early return'/'eager return':

public static int largest(int a, int b, int c) {
    if(a > b && a > c) {
        return a;
    }

    if(b > c) {
        return b;
    }

    return c;
}

Answer 3

During compilation time, your compiler cannot find the parallel else condition of (a>b) that is => if(a<=b)

what it will return if your input matches this block? So you should provide this
