Java program to perform multiplication of two number without using * operator

Java supports different types of Operators. Operators can be classified into numbers of categories: Arithmetic operators, Bitwise operators, Logical Operators, Conditional operators, Assignment Operators, Relational operators, Special operators, Increment Operators, Decrement operators. Java program to perform multiplication of two number without using * operator are given below:

Arithmetic Operators:

Arithmetic operators are addition, substraction, multiplication, division, and modulus. The symbol modulus (%) which divides one operand by another and returns the remainder as its output.

The following table lists the arithmetic operators:

Operator	Meaning
+	Addition or unary plus
–	Substraction or unary minus
*	Multiplication
/	Division
%	Modulus

Program:

import java.io.*;
import java.util.*;
class Multiplication{
public static void main(String args[])
{
Scanner sc= new Scanner(System.in);
System.out.println("Enter the 1st number");
int a=sc.nextInt();
System.out.println("Enter the 2nd number");
int b=sc.nextInt();
 int c=0;
for(int i=0;i<b;i++)
{
c=c+a;
}
System.out.println("The Multiplication of two numbers is "+c);
}
}

Compile:

javac Multiplication.java

Run:

java Multiplication

Output:

Enter the 1st number
10
Enter the 2nd number
5
The Multiplication of two numbers is 50

The Process of programming in java is divided into 3 phases:

1. Writing Simple Java Program: Create a simple java Program by typing it into a text editor. Then save the program with the same name as that of the class name. You can wrote simple java application in Eclipse also.

2. Compiling a Java Source File: After Completion of Java program, open Command prompt. Type the Command “ javac filename.java ” . If their is any error then remove first.

3. Running a Java Application: To run java Application in the command prompt ,type ” Filename.java” .
