public class ArithmeticOperatorDemo { // Demonstrate the basic arithmetic operators. public static void main(String args[]) { // arithmetic using integers System.out.println("Integer Arithmetic"); int i = 1 + 1; int n = i * 3;
```java class ArithmeticDemo { public static void main (String[] args){ int result = 1 + 2; // result is now 3 System.out.println(result); result = result - 1; // result is now 2 System.out.println(result); result = result * 2; // result is now 4 System.out.println(result...
In this particular program, the arithmetic operator “*” can be utilized to multiply the two specified float values: doublenum1=2.5; doublenum2=3.5; doubleresult=num1*num2; System.out.println("The multiplication of the numbers is: "+result); ...
1. Arithmetic Operators: Perform mathematical operations which include addition(+), subtraction(-), multiplication(*), division(/), modulus(%). Example: Output: 35 -11 276 0.5217391304347826 Explanation: The + operator adds the values 12 and 23, resulting the value of 35. The - operator sub...
