Check Whether the number is positive negative or Zero in java

Hello guys, welcome to lingarajtechhub.com . Today we are going to discuss whether the number is positive negative or zero in java.

Code:

package com.Else_if.java;
public class Else_If
 {
      public static void main(String[] args) {
	int n=-13; 
	   if(n>0)
		System.out.println("The value of " +n + " is positive ");
	   else if (n<0)
		System.out.println("The value of "+n + " is negative");
	    else
		System.out.println("zero");
	}

}

Line-1:

package com.Else_if.java

It is a java package , this package is created in a java project and it contains classes inside the package.

Line-2:

public class Else_If

“Else_If” is the class-name , class is a template used to create objects & class-name first letters must be capital. It is public means we can use this outside of the package.

Line-4:

public static void main(String[] args)

It is a main method in which we can execute a program.

public : It is an access modifier. The main() is public because we can access main() outside of the class , if main() can’t be public then JVM(Java Virtual Machine) can’t be called main() & code can’t be executed.
Static : static is a keyword in which the main method has to be static in which JVM can load the class into memory and call the main method without creating an instance.
Void : Void is a data type. It means no return type.
main(): Main is a 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-5:

int n=13

Here “n” is the variable and int (Integer) is a data type of the variable. n value is 13 which is Assigned .

Line-6 to Line-11:

if(n>0)

System.out.println(“The value of ” +n + ” is positive “);

else if (n<0)

System.out.println(“The value of “+n + ” is negative”);

else

System.out.println(“zero”)

Here we used the “Else_If” condition. The logic is to check first if the number is greater than 0 then it prints or shows positive. Then check “else if” block or second

condition , if it is less than zero then it prints negative .Otherwise it executes the “else” block and prints zero.
