 Write a program to convert Dotted Decimal Notation to binary Notation in java

Code:

import java.util.*;

class Test{

public static void main(String[] args){

Scanner scn = new Scanner(System.in);

System.out.println("Enter Dotted decimal Notation:");

String dec = scn.next();

int logic = 0;

String res = "";

String[] arr = dec.split("[.]",0);

for(int i=0;i<arr.length;i++){

int num = Integer.parseInt(arr[i]);

if(num> 255){

System.out.println("Invalid dotted decimal Notation");

logic = 1;

break;

}

String bin = toBin(num);

res = res + bin;

}

if(logic == 0){

System.out.println("Binary Notation "+res);

}

}

public static String toBin(int n){

String bin = Integer.toBinaryString(n);

int len = bin.length();

if(bin.length() < 8){

for(int i=0;i<8-len;i++){

bin = "0"+bin;

}

}

return bin;

}

}
