Write a method that takes 3 integer as parameters, return true if they are equal, return false otherwise without using if statement

I am trying to write a method that compares three integers without using the if statement. I tried the switch statement, but it wouldn't work. Eclipse shows case expressions must be constants.

Here is a snippet of my code:

public boolean multipleValue(int n1, int n2, int n3)
{
    boolean result = false;

    switch (n1)
    {
    case num2:
    case num3:
        result = true;
        break;
    default:
        result = false;
    }
    
    return result;
}
```
Solution

  • This line checks if a is equal to b and if b is equal to c. If both conditions are true, it returns true; otherwise, it returns false.

    return (a == b)&&(b == c);
