关系操作符:比较两个变量之间的关系
> 大于
>= 大于或等于
< 小于
<= 小于或等于
== 是否相等
!= 是否不等

关系操作符顶折
> 大于
>= 大于或等于
< 小于
<= 小于或等于
== 是否相等
!= 是否不等

public class HelloWorld {
public static void main(String[] args) {
int a = 5;
int b = 6;
int c = 5;

System.out.println(a>b); //返回 false
System.out.println(a>=c); //返回 true

System.out.println(a==b); //返回false
System.out.println(a!=b);//返回true

}
}

借助Scanner获取控制台输入的两个任意数字，然后使用
> 大于
>= 大于或等于
< 小于
<= 小于或等于
== 是否相等
!= 是否不等

判断两个值之间的关系

package com.weiliang;

import java.util.Scanner;

public class RelationalOperator {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
int number = scanner.nextInt();
System.out.println("第一个整数:" + number);
int number2 = scanner.nextInt();
System.out.println("第二个整数:" + number2);
System.out.println("比较" + number + ">" + number2 + ":" + (number > number2));
System.out.println("比较" + number + ">=" + number2 + ":" + (number >= number2));
System.out.println("比较" + number + "<" + number2 + ":" + (number < number2));
System.out.println("比较" + number + "<=" + number2 + ":" + (number <= number2));
System.out.println("比较" + number + "==" + number2 + ":" + (number == number2));
System.out.println("比较" + number + "!=" + number2 + ":" + (number != number2));

}
