Hellow guys, welcom to Lingarajtechhub.Today we are going to discuss find a Multiplication Table Using loop.
Code:
package com.control_loop.java; import java.util.Scanner; public class Multiplication_table { public static void main(String[] args) { Scanner sc= new Scanner (System.in); System.out.println("enter the number : "); int num=sc.nextInt(); for(int i=1;i<=10;i++) { System.out.println(""+num+" * "+i+" = " +(num*i)); } } }
Line:1
package com.Operators.Java;
- It is a java package which is a collection of classes and this package is created in a java project(Homework_operator) .
- Here com.operators.java is the name of our package.
Line:2
import java.util.Scanner;
- Scanner is a class in java
- . util package used for obtaining the input of the primitive types like int, double, etc. and strings .
Line:3
public class Multiplication_table
- Here “ Multiplication_table” is defined as a class which is a template used to create objects ,& to define object ,data type and method.
- It is defined as public because it can be accessed anywhere.
- It is the entry point to the application.
Line:4
public static void main(String[] args){
- This is the main () method of our java program.
- Every java program must contain the main() method.
- Public : It is the access modifier of the main function which must be public so that the JRE can access and execute this method.
- If a method is not public then access is restricted and it’s showing an error.
- Static : Static is a keyword in which the main method has to be static so that the JVM can load the class into memory and call the main method without creating an instance.
- Void : It means no return types.
- Main() : It is a function.
- String [] args :String means the collection of characters.
- String[] args represents a collection of strings that are separated by a space and can be typed directly into the program on the terminal.
Line:5
int num,i;
- Here we Declare 2 variables num,i which is integer type and int is a local variable.
Line:6
Scanner Sc = new Scanner(System.in);
- Here scanner is a class and Sc is the instance of the object which is the new Scanner. System.in is an argument.
Line:7
num=sc.nextInt();
- “num” is a variable that we take and sc is our instance name which is created for an object and nextInt() is a method of a Scanner object that reads in a string of digits or char and converts them into an int type.
Line:8
for(i=1; i<=10 ; i++ ) {
System.out.println(“+num+” * “ + i + ”=”+(num*i));
- for(initialization; condition; increment/decrement)
It is used when we want to perform initialization, condition & increment/decrement in one single line.
Line:9
System.out.println( );
- It means System is a class name and out is an instance of the System println is to print a new line and “+” means cocardinate.
