Info Tech Guide

The Java programming language provides operators that perform addition, subtraction, multiplication, and division. There's a good chance you'll recognize them by their counterparts in basic mathematics. The only symbol that might look new to you is "%", which divides one operand by another and returns the remainder as its result.

+ additive operator (also used for String concatenation)
- subtraction operator
* multiplication operator
/ division operator
% remainder operator


 The following program, ArithmeticDemo, tests the arithmetic operators.

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);

result = result / 2; // result is now 2
System.out.println(result);

result = result + 8; // result is now 10
result = result % 7; // result is now 3
System.out.println(result);

}
}

class ConcatDemo {
public static void main(String[] args){
String firstString = "This is";
String secondString = " a concatenated string.";
String thirdString = firstString+secondString;
System.out.println(thirdString);
}
}
