How to Make Basic Java programs:

Java is one of the best programming language to make GUI and many other departmental software for making computer handling software . Through java programming you can make games , calculators , ticket Machine and related software because it deals with some wide range of built in functions which every programming language do exist..

Here below is the Code through which you can easily make some basic four programs :


Even or Odd :

import java.util.Scanner;
public class EvenorOdd
{
 public static void main(String Args[])
 {
  int x;
  System.out.println("Enter the number");
  Scanner input = new Scanner(System.in);
  x=input.nextInt();
  
  if(x % 2 ==0)
   System.out.println("The number is even");
  else
   System.out.println("The number is odd");
 }
}

Radius :

import java.util.Scanner;
public class Radius {
 public static void main(String[] args) {
  Scanner scn= new Scanner(System.in);
  float rad;
  System.out.print("Please Enter Radius of a Circle: ");
  rad = scn.nextFloat();
  
  float pi = (float) Math.PI;
  float diam = 2*rad;
  float cir = 2*pi*rad;
  float area = pi*(rad*rad);
  
  System.out.printf("A Circle of Radius %s has: Diameter: %s Circumference: %s Area: %s ", rad, diam, cir, area); 
 }
}

Maximum and Minimum value :

import java.util.Scanner;

public class MaxMin
{
 public static void main(String arg[])
 {
  Scanner cp = new Scanner (System.in);
  
  int inputVal;
  int max = 0;
  int min = 0;

  for(int i=1; i<=5;i++)
  {
   System.out.println(String.format("Enter Value #%s: ", String.valueOf(i)));
   inputVal = cp.nextInt();
   if(i==1)
   {
    min = inputVal;
    max = inputVal;
   }
   if(inputVal > max) {
    max = inputVal;
   }
   if(inputVal < min)
   {
    min = inputVal;
   }
  }
  System.out.println(String.format("Max Value is %s.", max));
  System.out.println(String.format("Min Value is %s.", min));
 }
}


Spacing between digits :
import java.util.Scanner;

public class Spacing{
 
 public static void main(String[] args) {
  Scanner scn= new Scanner(System.in);
  
  int i;
  int maxminAllowed= 5;
  
  System.out.print("Enter 5 Digits: ");
  i = scn.nextInt();
   
  String s = String.valueOf(i);
  int charCount = s.length();
  
  if(charCount == maxminAllowed)
  {
   char[] charss  = s.toCharArray();
   System.out.printf("%s \t %s \t %s \t %s \t %s",charss[0],charss[1],charss[2],charss[3],charss[4]);
  }else if(charCount > maxminAllowed){
   System.out.printf("You can not enter Numbers Greater than %s", maxminAllowed);
   System.out.println("");
   main(args);
  }else {
   System.out.printf("You can not enter Numbers Less than %s", maxminAllowed);
   System.out.println("");
   main(args);
  }
 }
}
