java convert int to binary code example

Example 1: java integer to binary string

int n = 1000;
String s = Integer.toBinaryString(n);

Example 2: int to binary java

String binary = Integer.toBinaryString(num);

Example 3: Java program to convert integer value into binary

import java.util.*;
import java.util.Scanner;
public class IntegerToBinary
{
   public static void main(String[] args)
   {
      int num;
      String str = "";
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter the a number : ");
      num = sc.nextInt();
      // convert int to binary java
      while(num > 0)
      {
         int y = num % 2;
         str = y + str;
         num = num / 2;
      }
      System.out.println("The binary conversion is : " + str);
      sc.close();
   }
}

Example 4: java int to binary string

public static String makeBinaryString(int n) {
	StringBuilder sb = new StringBuilder();
	while (n > 0) {
    sb.append(n % 2);
		n /= 2;
	}
  	sb.reverse();  	
  	return sb.toString();
}

Example 5: binary number input in int java

Integer.toBinaryString(int i)
