Hello guys, welcome to Lingarajtechhub.com Today we are going to discuss how to take three numbers from the user and print the greatest number.
code:
package com.control.java;
import java.util.Scanner;
public class Greatest_number {
public static void main(String[] args) {
int a,b,c;
Scanner Sc=new Scanner(System.in);
System.out.println("enter the value of a,b,c");
a=Sc.nextInt( );
b=Sc.nextInt( );
c=Sc.nextInt( );
if(a>b)
{
if(a>c)
System.out.println("a is greater");
else
System.out.println("c is greater");
}
else
{
if(b>c)
System.out.println("b is greater");
else
System.out.println("c is greater");
}
}
}
line-2:
Package com.control.java
It is a java package( com.control.java) which is a collection of classes and this package is created in a java project .
Line-3:
❖ 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-5:
❖ public class Greatest_number {
>>–Here Greatest_number is defined as a class which is a template used to create objects and to define object data types and methods .
>–and it’s defined as public because it can be accessed anywhere .
Line-7:
❖ public static void main(String[] args)
>>– it is a main method in which we can execute a program //public :it is an access modifier of the main function which must be public so that the JVM which is (Java Virtual Machine)can access and execute this method.
//If a method is not public, then access is restricted and its showing error //static is a keyword in which main method has must to be static in which JVM can load the class into memory and call the main method without creating an instance //void it means no return type
//main() is function string[]args : string means collection of characters ,String[] args represents a collection of Strings that are separated by a space and can be typed into the program on the terminal directly
Line-8:
❖ int a,b,c;
>>– here we declare a,b,c as a variable which is integer type
Line-9:
❖ Scanner sc=new Scanner(System.in);
>>–it means here scanner is a class and Sc is the instance of the object which is new Scanner.System.in is an argument
Line-10:
❖ System.out.println(“Enter the value of a,b,c “);
>>– it means System is a class name and out is an instance of the System println is print a new line
Line-11:
❖ a=sc.nextInt();
>>– here a is a variable that we take and Sc is our instance name which is create for a object and nextInt() is a method method of a Scanner object reads in a string of digits or char and converts them into an int type
Line-12:
❖ b=sc.nextInt();
>>– here b is a variable that we take and Sc is our instance name which is created for an object and nextInt() is a method method of a Scanner object that reads in a string of digits or char and converts them into an int type.
Line-13:
❖ c=sc.nextInt();
>>– here c is a variable that we take and Sc is our instance name which is create for a object and nextInt() is a method method of a Scanner object reads in a string of digits or char and converts them into an int type
Line-15:
- if(a>b)
>>–Here loop started and a is greater than b.
Line-17:
- if(a>c)
>>–Here a is greater than c.
Line-19:
❖ System.out.println(“a is greater” );
>>– it means System is a class name and out is an instance of the System println is print a new line .
Line-20:
- Else
>>–loop
Line-21:
❖ System.out.println(“c is greater” );
>>– it means System is a class name and out is an instance of the System println is print a new line .
Line-23:
❖ else
>>–loop.
Line-25:
- if(b>c)
>>–Here a is greater than c.
Line-26:
❖ System.out.println(“b is greater” );
>>– it means System is a class name and out is an instance of the System println is print a new line .
Line-27:
- Else
>>–loop
Line-28:
❖ System.out.println(“c is greater” );
>>– it means System is a class name and out is an instance of the System println is print a new line.
