Day6 Java运算符1

算术运算符

package operator;

public class Demon02 {
    public static void main(String[] args) {
        long    a = 123132123;
        int b = 123;
        short c =100;
        byte    d  =8;
        System.out.println(a+b+c+d);
        System.out.println(b+c+d);
        System.out.println((double)c+d);
         System.out.println(c%b);
        System.out.println(c!=b);
    }
}


```java
在这里插入代码片

//关系运算符

package operator;

public class Demon03 {
public static void main(String[] args) {
int a = 10;
int b = 20;
int c = 30;

    System.out.println(a>b);
    System.out.println(a 
}
 

另外，算术运算符还有++，--
关系运算符还有inranceif
还有其他几类没讲，明天再学
