The java.lang.Integer.toBinaryString() method returns a string representation of the integer argument as an unsigned integer in base 2. It accepts an argument in Int data-type and returns the corresponding binary string.
Syntax:
public static String toBinaryString(int num) Parameter : The function accepts a single mandatory parameter num num - This parameter specifies the number to be converted to binary string. It is of int data-type
Return Value: This function returns the string representation of the unsigned Integer value represented by the argument in binary (base 2).
Examples:
Input : 10 Output : 1010 Input : 9 Output : 1001
// Java program to demonstrate// java.lang.Integer.toBinaryString() methodimport java.lang.Math;  class Gfg1 {      // driver code    public static void main(String args[])    {          int l = 10;        // returns the string representation of the unsigned int value        // represented by the argument in binary (base 2)        System.out.println("Binary is " + Integer.toBinaryString(l));          l = 9;        System.out.println("Binary is " + Integer.toBinaryString(l));    }} |
Output:
Binary is 1010 Binary is 1001
