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

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

Code:

package com.table_oops_class_obj.java;

public class Table {
	String type;
	int price;
	
	void tab_input() {
		type="wood";
		price=5000;
	}
	void tab_disp() {
		System.out.println("Table type:"+type);
		System.out.println("Table price:"+price);
	}

	public static void main(String[] args) {
		Table t=new Table();
		t.tab_input();
		t.tab_disp();
	}

}

Line-1:

package com.table_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 Table

“Table” 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 type

Here the type is the variable and String is a class. It is not a data type.

Line-5:

int price

Here price is the variable and int (Integer) is a data type of the variable.

void tab_input() {

type=”wood”;

price=5000;

}

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

void tab_disp() {

System.out.println(“Table type:”+type);

System.out.println(“Table price:”+price);

}

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

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.
