java运算符实验报告(数据类型和运算符的实验报告)

实验目的

本次实验的目的是了解Java运算符的使用与其产生的效果，通过实验进一步巩固自己的Java语言基础，提高对Java的理解与应用水平。

实验过程与结果

本次实验我编写了一段Java程序，分别使用了数学运算符、赋值运算符、逻辑运算符、比较运算符和三元运算符，具体代码如下：

public class OperatorTest {
    public static void main(String[] args) {
        int a = 6;
        int b = 4;
        
        // 数学运算符
        int sum = a + b;
        int sub = a - b;
        int mul = a * b;
        double div = (double)a / b;
        int mod = a % b;
        System.out.println("addition: " + sum + ", subtraction: " + sub +
            ", multiplication: " + mul + ", division: " + div + ", modulus: " + mod);
        
        // 赋值运算符
        int c;
        c = a + b;
        System.out.println("c = a + b: " + c);
        c += b;
        System.out.println("c += b: " + c);
        c -= b;
        System.out.println("c -= b: " + c);
        c *= b;
        System.out.println("c *= b: " + c);
        c /= b;
        System.out.println("c /= b: " + c);
        c %= b;
        System.out.println("c %= b: " + c);
        
        // 逻辑运算符
        boolean x = true;
        boolean y = false;
        boolean z = (x && y) || (x || !y);
        System.out.println("z = " + z);
        
        // 比较运算符
        boolean e = (a == b);
        boolean f = (a != b);
        boolean g = (a  b);
        boolean i = (a = b);
        System.out.println("equal: " + e + ", not equal: " + f + ", less than: " +
            g + ", greater than: " + h + ", less than or equal to: " + i + ", greater than or equal to: " + j);
            
        // 三元运算符
        int m = (a > b) ? a : b;
        System.out.println("maximum between a and b is: " + m);
    }
}

addition: 10, subtraction: 2, multiplication: 24, division: 1.5, modulus: 2
c = a + b: 10
c += b: 14
c -= b: 10
c *= b: 40
c /= b: 10
c %= b: 2
z = true
equal: false, not equal: true, less than: false, greater than: true, less than or equal to: false, greater than or equal to: true
maximum between a and b is: 6
