7.1 Review: what does this method do?

A. Introduction

1. We have discussed method calling, parameter passing and return values in Introduction to Java. For a quick review, please see this class below and discuss what the outputs will be.

class _7_1 {
  public static int max(int x, int y, int z ){
    if(x>=y && x>=z) return x;
    else if(y>=z && y>=x) return y;
    else return z;
  } 
  public static void max2(int x, int y, int z, int m ){
    if(x>=y && x>=z) m=x;
    else if(y>=z && y>=x) m=y;
    else m=z;
  }
  public static void main(String[] args) {
    int a=710, b=109, c=-870;
    int m=0;
    System.out.println(max(a, b, c));
    max2(a, b, c, m);
    System.out.println(m);
  }
}

B. Watch .... (Slides)

C. Try this in class:

Write a function to take 3 int parameters and return the smallest of them. Call this function in main( ) to test with both positive and negative input values.
