代码:

package com;

public class BasicOperations {
    public static void main(String[] args) {
        int tempFirstInt, tempSecondInt, tempResultInt;
        double tempFirstDouble, tempSecondDouble, tempResultDouble;

        tempFirstInt = 15;
        tempSecondInt = 4;

        tempFirstDouble = 1.2;
        tempSecondDouble = 3.5;

        //Addition
        tempResultInt = tempFirstInt + tempSecondInt;
        tempResultDouble = tempFirstDouble + tempSecondDouble;

        System.out.println("" + tempFirstInt + " + " + tempSecondInt + " = " +tempResultInt);
        System.out.println("" + tempFirstDouble + " + " + tempSecondDouble + " = " + tempResultDouble);

        //Subtraction
        tempResultInt = tempFirstInt - tempSecondInt;
        tempResultDouble = tempFirstDouble - tempSecondDouble;

        System.out.println("" + tempFirstInt + " - " + tempSecondInt + " = " + tempResultInt);
        System.out.println("" + tempFirstDouble + " - " + tempSecondDouble + " = " + tempResultDouble);

        //Multiplication
        tempResultInt = tempFirstInt *  tempSecondInt;
        tempResultDouble = tempFirstDouble * tempSecondDouble;

        System.out.println("" + tempFirstInt + " * " + tempSecondInt + " = " + tempResultInt);
        System.out.println("" + tempFirstDouble + " * " + tempSecondDouble + " = " + tempResultDouble);

        //Division
        tempResultInt = tempFirstInt / tempSecondInt;
        tempResultDouble = tempFirstDouble / tempSecondDouble;

        System.out.println("" + tempFirstInt + " / " + tempSecondInt + " = " + tempResultInt);
        System.out.println("" + tempFirstDouble + " / " + tempSecondDouble + " = " + tempResultDouble);

        //Modules
        tempResultInt = tempFirstInt % tempSecondInt;
        System.out.println("" + tempFirstInt + " % " + tempSecondInt + " = " +tempResultInt);

    }
}

运行结果:

15 + 4 = 19
1.2 + 3.5 = 4.7
15 - 4 = 11
1.2 - 3.5 = -2.3
15 * 4 = 60
1.2 * 3.5 = 4.2
15 / 4 = 3
1.2 / 3.5 = 0.34285714285714286
15 % 4 = 3
