方法重载

package day05;

public class OverloadDemo {
    /*  使用方法重载思想设计比较两个数是否相同的方法，
       兼容全整数类型（byte、short、int、long）*/
    public static void main(String[] args) {
        short a = 10;
        short b = 20;
        System.out.println(compare(a, b));
    }

    public static boolean compare(int a, int b) {
        return a == b;
    }

    public static boolean compare(byte a, byte b) {
        return a == b;
    }

    public static boolean compare(short a, short b) {
        return a == b;
    }

    public static boolean compare(long a, long b) {
        return a == b;
