These tutorials will introduce you to Java programming Language. You'll compile and run your Java application, using Sun's JDK. It's very easy to learn java programming skills, and in these parts, you'll learn how to write, compile, and run Java applications. Before you can develop corejava applications, you'll need to download the Java Development Kit (JDK).

PART-2


Java Arithmetic Operators

The Java programming language has includes five simple arithmetic operators like are + (addition), - (subtraction), * (multiplication), / (division), and % (modulo). The following table summarizes the binary arithmetic operators in the Java programming language.

The relation operators in Java are: ==, !=, <, >, <=, and >=. The meanings of these operators are:

Use Returns true if
op1 + op2 op1 added to op2
op1 - op2  op2 subtracted from op1
op1 * op2  op1 multiplied with op2
op1 / op2  op1 divided by op2
op1 % op2  Computes the remainder of dividing op1 by op2

The following java program, ArithmeticProg , defines two integers and two double-precision floating-point numbers and uses the five arithmetic operators to perform different arithmetic operations. This program also uses + to concatenate strings. The arithmetic operations are shown in boldface. 

public class ArithmeticProg {
	public static void main(String[] args) {

	//a few numbers
	int i = 10;
	int j = 20;
	double x = 10.5;
	double y = 20.5;

	//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("Modulus");
	System.out.println(" i % j = " + (i % j));
	System.out.println(" x % y = " + (x % y));

    }
