Program to create two threads, one for Prime number and other for Non-prime number

This is a simple program which prints prime and non-prime numbers from 1 to 10. 
PROGRAM
class Prime extends Thread {
 
 public void run() {
  
  for(int i=1; i<=10; i++) {
   if(i==2 || i==3 || i==5 || i==7)
    System.out.println("Prime no. : " + i);
  }
 }
}

class NonPrime extends Thread {
 
 public void run() {
  
  for(int i=1; i<=10; i++) {
   if(i==4 || i==6 || i==8 || i==9 || i==10)
    System.out.println("Non-Prime no. : " + i);
  }
 }
}

public class PrimeNotPrimeThread {

 public static void main(String[] args) {
  
  new Prime().start();
  new NonPrime().start();
 }
}
OUTPUT 
C:\>javac PrimeNotPrimeThread.java
C:\>java PrimeNotPrimeThread
Prime no. : 2
Prime no. : 3
Prime no. : 5
Prime no. : 7
Non-Prime no. : 4
Non-Prime no. : 6
Non-Prime no. : 8
Non-Prime no. : 9
Non-Prime no. : 10

Program to define a class 'employee' with data members as empid, name and salary. Accept data for 5 objects using Array of objects and print it.

This program demonstrates you the array of objects.  Array of object  is the collection of objects of the same class. The given syntax will define an array of reference therefore assign object to individual reference in the array to declare the array of object. The syntax to define array of object is: <class-name> <array-name> [size]; For example, the following statement will define an array of object having size 6 references to the class  Box . Box b[6]; For creating an array of objects (allocating memory) you have to write down the following statements for (int i=0; i<6; i++) { b[i] = new Box(); // Assigning object to individual reference in the array. } PROGRAM import java.util.Scanner; public class Employee { int empid; String name; float salary; public void getInput() { Scanner in = new Scanner(System.in); System.out.print("Enter the empid :: "); empid = in.nextInt(); System.out.print("Enter the name :: ");

Define a class Student with four data members such as name, roll no.,sub1, and sub2. Define appropriate methods to initialize and display the values of data members. Also calculate total marks and percentage scored by student.

In this program, first we first create a class  Student  which have data members  name, roll_no, sub1, sub2  and one method to read data here  getdata( )  method and show the result here  show( )  method. We have used  java.io.BufferedReader  class to read data from keyboard at runtime. Then we have created an object of Student class in  StudentDemo  class and called the methods of Student class. When you compile the code using  javac StudentDemo.java  command two .class files will be created which are  Student.class  and  StudentDemo.class , this has the advantage that you can reuse your .class file somewhere in other projects without compiling the code again. You can create as many classes as you want but writing many classes in a single file is not recommended as it makes code difficult to read rather you can create single file for every class. You can also group classes in packages for easily managing your code. PROGRAM import java.lang.*; import java.io.*; class Student
