实际上java与c的运算符近乎一样

1.关系运算符

public class laal {    public static void main(String args[]) {     if(5>2)         System.out.println("返回值："+(5>2));     if(true)         System.out.println("Hello java!");     if((3+6)==(3-6))         System.out.println("I like java!");    }}

返回值：trueHello java!

2.递增与递减运算符

public class Test {    public static void main(String args[]) {        int a = 3 , b = 3;                System.out.print("a = "+a);        System.out.println(" ,a++="+(a++)+" ,a="+a);        System.out.print("b = "+b);        System.out.println(" ,++b="+(++b)+" ,b="+b);    }}

a = 3 ,a++=3 ,a=4b = 3 ,++b=4 ,b=4

3.逻辑运算符

public class logic {        public static void main(String args[]) {            int a = 56;                   if((a<0)||(a>100))                System.out.println("输入的数据有错误!");            if((a<60)&&(a>49))                System.out.println("准备补考吧！");       }}

准备补考吧！
