Write a program to display properties of School using class & object in the oops concept

Hello guys, welcome to lingarajtechhub.com. Today we are going to discuss the display properties of School using class & object in the oops concept.

Code:

package com.School_oops_class_obj.java;

public class School {
	String name,address;
	
	void school_Input() {
		name="Cime";
		address="Rasulgad";
	}
	void school_Display() {
		System.out.println("school name:"+name);
		System.out.println("school address:"+address);
	}

	public static void main(String[] args) {
		 School s=new  School();
		 s.school_Input();
         s.school_Display();
	}

}

Line-1:

package com.School_oops_class_obj.java;

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

Line-3:

public class School

“School” 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:

String name,address

Here the name , Address are the variables and String is a class. It is not a data type.

Line-6:

void school_Input() {

name=”Cime”;

address=”Rasulgad”;

}

In this line we create a method whose name takes school_Input() where store properties values.

Line-10:

void school_Display() {

System.out.println(“school name:”+name);

System.out.println(“school address:”+address);

}

In this line we create a method whose name takes school_Display().system is a predefined class .Out is a static variable of type printstream present in system class. Println shows the result.

Line-15:

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.
