javase-arithmetic operators

Arithmetic operators include: + 、-、 *,/,%, + + 、--

Code:

Package com.java.chap02;

public class Demo07 {

public static void Main (string[] args) {
int a=10;
int b=3;
+ operator
System.out.println (A + "+" +b+ "=" + (a+b));
-Operator
System.out.println (A + "-" +b+ "=" + (a) ");
* operator
System.out.println (A + "*" +b+ "=" + (a*b));
/operator
System.out.println (A + "/" +b+ "=" + (A/b));
% operator
System.out.println (A + "%" +b+ "=" + (a%b));

int a1=1;
a1++; Indicates that the assignment operation is done first, and then the self-increment
int b1=a1++;
System.out.println ("b1=" +b1);
System.out.println ("a1=" +a1);

System.out.println ("================");

int a2=1;
++a2; means to increment first and then do assignment
int b2=++a2;
System.out.println ("b2=" +b2);
System.out.println ("a2=" +a2);

}
}
