Java 赋值运算符示例

 Java 运算符

下面的示例显示了赋值运算符和复合赋值运算符的用法:

• = 赋值运算符
• += 加法 与 赋值运算符
• -= 减法 与 赋值运算符
• *= 乘法 与 赋值运算符
• /= 除法 与 赋值运算符
• %= 取模与赋值运算符

public class MyClass {
  public static void main(String[] args) {
    float a = 25f;

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

    //加法AND赋值运算符
    a += 5;
    System.out.println("a += 5; makes a = "+ a);

    //减法与赋值运算符
    a -= 8;
    System.out.println("a -= 8; makes a = "+ a);

    //乘法与赋值运算符
    a *= 4;
    System.out.println("a *= 4; makes a = "+ a);

    //除法与赋值运算符
    a /= 2;
    System.out.println("a /= 2; makes a = "+ a);

    //模与赋值运算符
    a %= 7;
    System.out.println("a %= 7; makes a = "+ a);
  }
} 

上述代码的输出将是:

a = 25.0
a += 5; makes a = 30.0
a -= 8; makes a = 22.0
a *= 4; makes a = 88.0
a /= 2; makes a = 44.0
a %= 7; makes a = 2.0
