关系运算符用来比较两个值的关系，其运算结果是boolean型，当运算符对应的关系成立是，运算结果真为true，假为false。
假设变量a的值为10，变量b的值为5：
| 关系运算符 | 说明 | 举例 |
| > | 左操作数的值大于右操作数的值为真 | (a>b)为真 |
| < | 左操作数的值小于右操作数的值为真 | (a<b)为假 |
| >= | 左操作数的值大于或等于右操作数的值为真 | (a>=b)为真 |
| <= | 左操作数的值小于或等于右操作数的值为真 | (a<=b)为假 |
| == | 左操作数的值等于右操作数的值为真 | (a==b)为假 |
| != | 左操作数的值不等于右操作数的值为真 | (a!=b)为真 |
实例：
public class Main {
public static void main(String[] args) {
int a = 5;
int b = 10;
System.out.println("a == b = " + (a == b) );
System.out.println("a != b = " + (a != b) );
System.out.println("a > b = " + (a > b) );
System.out.println("a < b = " + (a < b) );
System.out.println("a >= b = " + (a >= b) );
System.out.println("a <= b = " + (a <= b) );
}
}运行结果如下：
a == b = false a != b = true a > b = false a < b = true a >= b = false a <= b = true
