Java Program to convert Decimal to Binary : 

public class DecimalToBinary {
 
 public void toBinary(int number){
 int binary[] = new int[25];
 int n = 0;
 // Convert Decimal to Binary
 while(number > 0){
 binary[n++] = number%2;
 number = number/2;
 }
 // Print Binary number
 for(int i = n-1;i >= 0;i--){
 System.out.print(binary[i]);
 }
 }
 
 public static void main(String[] args){
 DecimalToBinary obj = new DecimalToBinary();
 obj.toBinary(14);
 }
}

Output :

1110

 

Java Program to convert Decimal to Binary using Scanner class :


import java.util.Scanner;

public class DecimalToBinary {

public void toBinary(int number){
int binary[] = new int[14];
int n = 0;

// Convert Decimal to Binary
while(number > 0){
binary[n++] = number%2;
number = number/2;
}

// Print Binary Number
for(int i = n-1;i >= 0;i--){
System.out.print(binary[i]);
}
}

public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter a number: ");
int num= scanner.nextInt();
DecimalToBinary obj = new DecimalToBinary();
obj.toBinary(num);

}
}

Output :

Enter a number: 14
