Java Integer toBinaryString() Method
Java toBinaryString()
method is the part of the Integer
class of the java.lang
package. This method is used to return the binary equivalent of base 2 of the value passed as an unsigned integer as a String.
For example: for the value 54, the equivalent binary string returned will be 110110.
Syntax:
public static String toBinaryString (int i)
Parameters:
The parameter passed is the integer value of which the string representation of the equivalent binary of base 2 is to be returned.
Returns:
Returns the String representation of the parameter passed as equivalent base 2 binary value.
Example 1:
Here, a positive and a negative number is taken for a better understanding of the method.
import java.lang.Integer;
public class StudyTonight
{
public static void main(String[] args)
{
int i = 121;
int j = -53;
System.out.println("Actual number is = " + i);
//returns the integer value in binary base 2 as a string
System.out.println("Binary equivalent is = " + Integer.toBinaryString(i));
System.out.println("Actual number is = " + j);
//returns the integer value in binary base 2 as a string
System.out.println("Binary equivalent is = " + Integer.toBinaryString(j));
}
}
Actual number is = 121
Binary equivalent is = 1111001
Actual number is = -53
Binary equivalent is = 11111111111111111111111111001011
Example 2:
Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent output.
import java.util.Scanner;
public class StudyTonight
{
public static void main(String[] args)
{
try
{
System.out.print("Enter the Number = ");
Scanner sc = new Scanner(System.in);
int i = sc.nextInt();
System.out.println("Actual Number is = " + i);
//returns the integer value in binary base 2 as a string
System.out.println("Binary representation is = " + Integer.toBinaryString(i));
}
catch(Exception e)
{
System.out.println("Invalid Number");
}
}
}
Enter the Number = 33
Actual Number is = 33
Binary representation is = 100001
*****************************************
Enter the Number = -31
Actual Number is = -31
Binary representation is = 11111111111111111111111111100001
*******************************************
Enter the Number = 0x454
Invalid Number
