学习了Java各种运算符的使用

认识并学习了Java的各种运算符

源代码：

public class Test {

public static void main(String args[]) {
int a = 10;
int b = 20;
int c = 25;
int d = 25;
System.out.println("a + b = " + (a + b) );
System.out.println("a - b = " + (a - b) );
System.out.println("a * b = " + (a * b) );
System.out.println("b / a = " + (b / a) );
System.out.println("b % a = " + (b % a) );
System.out.println("c % a = " + (c % a) );
System.out.println("a++ = " + (a++) );
System.out.println("a-- = " + (a--) );
// 查看 d++ 与 ++d 的不同
System.out.println("d++ = " + (d++) );
System.out.println("++d = " + (++d) );
}
}
