Day 2：基本算术操作
package cn.itcast.demo2;
public class BasicOperations {
public static void main(String[] args) {
int tempFirstInt,tempSecondInt,tempResultInt;
double tempFirstDouble,tempSecondDouble,tempResultDouble;
tempFirstInt =20;
tempSecondInt = 30;
tempFirstDouble = 3.8;
tempSecondDouble = 25.8;
//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);
//Modulus
tempResultInt = tempFirstInt % tempSecondInt;
System.out.println("" + tempFirstInt + " % " + tempSecondInt + " = " + tempResultInt);
}
}
运算结果如下
