The Java programming language supports various arithmetic operators for all floating point
and integer numbers. These operators are (+)(addition), (-)(subtraction),(*)
(multiplication), (/)(division), and (%)(modulo). The following table summarizes the
binary arithmetic operations in the Java programming language.
Operator Use Description

So Let’s take an example to understand operators better

public class MyClass {
	public static void main(String[] args) {
		//a few numbers
		int i = 37;
		int j = 42;
		double x = 27.475;
		double y = 7.22;
		System.out.println("Variable values...");
		System.out.println(" i = " + i);
		System.out.println(" j = " + j);
		System.out.println(" x = " + x);
		System.out.println(" y = " + y);
		//adding numbers
		System.out.println("Adding...");
		System.out.println(" i + j = " + (i + j));
		System.out.println(" x + y = " + (x + y));
		//subtracting numbers
		System.out.println("Subtracting...");
		System.out.println(" i - j = " + (i - j));
		System.out.println(" x - y = " + (x - y));
		//multiplying numbers
		System.out.println("Multiplying...");
		System.out.println(" i * j = " + (i * j));
		System.out.println(" x * y = " + (x * y));
		//dividing numbers
		System.out.println("Dividing...");
		System.out.println(" i / j = " + (i / j));
		System.out.println(" x / y = " + (x / y));
		//computing the remainder resulting from dividing numbers
		System.out.println("Computing the remainder...");
		System.out.println(" i % j = " + (i % j));
		System.out.println(" x % y = " + (x % y));
		//mixing types
		System.out.println("Mixing types...");
		System.out.println(" j + y = " + (j + y));
		System.out.println(" i * x = " + (i * x));
	}
}

OUTPUT:

The output from this program is:
Variable values...
i = 37
j = 42
x = 27.475
y = 7.22
Adding...
i + j = 79
x + y = 34.695
Subtracting...
i - j = -5
x - y = 20.255
Multiplying...
i * j = 1554
x * y = 198.37
Dividing...
i / j = 0
x / y = 3.8054
Computing the remainder...
i % j = 37
x % y = 5.815
Mixing types...
j + y = 49.22
i * x = 1016.58
