java的运算符

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：true Hello 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=4 b = 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！
