Java lang.Integer.toBinaryString() method (original) (raw)

Last Updated : 05 Dec, 2018

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 `

// Java program to demonstrate // java.lang.Integer.toBinaryString() method import 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
