## 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:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
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:

1 |
javac Multiplication.java |

### Run:

1 |
java Multiplication |

### Output:

1 2 3 4 5 |
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” .
