比较运算符

public class Demo08Operator {
    public static void main(String[] args) {
        System.out.println(10 > 5);
        int num1 = 10;
        int num2 = 12;
        System.out.println(num1 < num2);
        System.out.println(num2 >= 100);
        System.out.println(num2 <= 100);
        System.out.println(num2 <= 12);
        System.out.println(10 == 10);
        System.out.println(20 != 25);
        System.out.println(20 != 20);
        int x = 2;
        // System.out.println(1 < x < 3); // 错误写法！编译报错！不能连着写。
    }
}
