关系运算和逻辑运算的应用

package ccc;public class Student {    public static void main(String[] args) {        // TODO 自动生成的方法存根        boolean bl=true;        boolean b2=false;                int xl=3,x2=5,x3=10; //定义变量                System.out.println(bl+"&&"+b2+"="+(bl&&b2)); //判断boolean型变量bl和b2的与或非逻辑关系                System.out.println(bl+"||"+b2+"="+(bl||b2));                System.out.println("!"+b2+"="+(!b2));                System.out.println("xl>x2&&x1<x3 " +(xl>x2&&xl<x3));                System.out.println("xl>x2||xl<x3 " +(xl>x2||xl<x3));                System.out.println("!(xl>x2 "+(!(xl>x2)));    }}
