AWT Program to display the given input on button click

By Sidharth Patnaik -
This is a program which will accept the input from the keyboard and on clicking the button, it will show the given input. This program is compiled in Eclipse. This is a basic program in Java using AWT where a single TextField, Label and a Button is used.

Screenshot


The Code: 
package dProBuk;

import java.awt.Button;
import java.awt.Frame;
import java.awt.GridLayout;
import java.awt.Label;
import java.awt.TextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class SimpleLayoutAWT implements ActionListener
{
 TextField t;
 Label l;
 Button b;
 public SimpleLayoutAWT() {
  // TODO Auto-generated constructor stub
  Frame f=new Frame("Simple Frame");
  t=new TextField("Enter the Name");
  l=new Label("");
  b=new Button("Show !");
  f.setLayout(new GridLayout(3,1));
  f.setVisible(true);
  f.setSize(500,200);
  f.add(t);
  f.add(b);
  f.add(l);
  b.addActionListener(this);
  f.addWindowListener(new WindowAdapter() {
          public void windowClosing(WindowEvent windowEvent){
              System.exit(0);
           }        
        });    
 }
 public static void main(String []args)
 {
  new SimpleLayoutAWT();
 }

 @Override
 public void actionPerformed(ActionEvent e) {
  // TODO Auto-generated method stub
  l.setText("Hello "+t.getText());
 }

}

Non Restoring Division Algorithm Implementation in C

This  is a Dynamic program for the implementation of the NON RESTORING Division Algorithm in C Language. Non Restoring Division uses Left Shift Operations, Twos' Compliment and Binary Addition. Screenshots[Demo] The Code #include<stdio.h> #include<malloc.h> int *a,*q,*m,*mc,*c,n,d; int powr(int x,int y) { int s=1,i; for(i=0;i<y;i++) s=s*x; return s; } void print(int arr[],int n) { int i; for(i=0;i<n;i++) printf("%d ",arr[i]); } void bin(int n, int arr[]){ int r, i = 0; do{ r = n % 2; n /= 2; arr[i] = r; i++; }while(n > 0); } void set(int array[], int x){ int i,tmp[20]={0}; for(i = x -1; i >=0; i--) tmp[x-1-i]=array[i]; for(i=0;i<x;i++) array[i]=tmp[i]; } int len(int x) { int i=0; while(powr(2,i)<=x) i++; return ++i; } void addBinary(int a1[], int a2[]) { int bi[2]={0},ca[20]={0}; int t=len(n),tmp=0; int *su=(int*)malloc(sizeof(int)*len(n)); while(t...

Hackerrank Modified Kaprekar Numbers Solution

By Sidharth Patnaik -

This is the solution to the Modified Kaprekar Numbers found in the implementation section of the algorithm domain in Hackerrank. A modified Kaprekar number is a positive whole number n with d digits, such that when we split its square into two pieces - a right hand piece r with d digits and a left hand piece l that contains the remaining d or d−1 digits, the sum of the pieces is equal to the original number (i.e. l + r = n) . Screenshot The Code def sendKap(x,s): y=x*x y=str(y) s1=y[:len(y)/2:] s2=y[len(y)/2::] s3=int(s1)+int(s2) if(s3==x): s.append(str(x)) st=input() en=input() s=[] for i in range(st,en+1): if(i>9): sendKap(i,s) elif(i==1): s.append(str(i)) elif(i==9): s.append(str(i)) if(len(s)==0): print 'INVALID RANGE' else: print ' '.join(s) Got any problems feel free to comment them here !

This is an implementation of the Bit Stuffing popularly used in data communication, also known as one of the concepts of Framing data bits. To know more please  click here. Sample Output: This is a sample output with data binary data entered as 11001111110. Program Code: import java.util.*; public class BitStuffing { public static void main(String[] args) { System.out.print("Enter the Binary message: "); Scanner sn=new Scanner(System.in); String data = sn.nextLine(); String res = new String(); String out=new String(); int counter = 0; for(int i=0;i<data.length();i++) { if (data.charAt(i)!='1' && data.charAt(i)!='0') { System.out.println("Enter only Binary values!!!"); return; } ...
