Convert integer type data into binary, octal and
hexadecimal
In this section, you will learn how to convert an
integer type data into binary, octal and hexadecimal. The java.lang package
provides the facility for converting the data integer into binary, octal, and
hexadecimal. The following program helps you to convert into these. toBinaryString()
method converts integer type data into binary, toHexString()
method converts integer type into hexadecimal and toOctalString() method converts integer into octal type data.
Description of code:
toBinaryString(int in):
This is the method that takes an integer type value and returns the string
representation of unsigned integer value that will represent the data in binary
(base 2).
toHexString(int in):
This is the method that takes an integer type value and converts in
hexadecimal or in an unsigned integer (base 16).
toOctalString(int in):
This is the method that takes an integer type value and converts it into octal
type data. The octal type data has base 8.
Here is the code of program:
public class DataConversion{
public static void main(String[] args) {
System.out.println("Data types conversion example!");
int in = 50;
System.out.println("Integer: " + in);
//integer to binary
String by = Integer.toBinaryString(in);
System.out.println("Byte: " + by);
//integer to hexadecimal
String hex = Integer.toHexString(in);
System.out.println("Hexa decimal: " + hex);
//integer to octal
String oct = Integer.toOctalString(in);
System.out.println("Octal: " + oct);
}
}
