Week 2: Methods, strings and lists/6b. Return the middle number

Write the method

middle

...which takes three integers as parameters. The method returns the middle of the numbers in order of magnitude.




Example method calls:
public static void main(String[] args) {
    System.out.println(middle(1, 3, 2);
    int mid = middle(8, 9, 7);
    System.out.println(mid);
}

Program outputs:
2
8










import java.util.Random;

public class Test{
    public static void main(String[] args){
        final Random r = new Random();
        
        
        Object[][] p = {{1,4,3}, {121,145,94}, {20,30,40}, {9,7,8}, {99,77,88}};
        for (Object[] pa : p) {
            System.out.print("Testing with parameters ");
            System.out.println(pa[0] + ", " + pa[1] + ", " + pa[2]);
            System.out.print("Middle: ");
            System.out.println(middle((Integer) pa[0], (Integer) pa[1], (Integer) pa[2]));
            System.out.println("");
        }
    }


    public static int middle(int int1, int int2, int int3) {
        int middle = 0;
        
        // 2-1-3, 3-1-2
        if ((int1 > int2 && int1 < int3) || (int3 < int1 && int1 < int2)) {
            middle = int1;
        } 
        // 1-2-3, 3-2-1
        else if ((int2 > int1 && int2 < int3) || (int2 > int3 && int2 < int1)) {
            middle = int2;
        } 
        // 2-3-1, 1-3-2
        else {
            middle = int3;
        }

        return middle;
    }
