Convert one base to other bases in a single Java Program
Let’s say we have an Octal number. To convert Octal to other bases like binary, hexadecimal, etc, the Java code is as follows −
Example
public class Demo{
public static String base_convert(String num, int source, int destination){
return Integer.toString(Integer.parseInt(num, source), destination);
}
public static void main(String[] args){
String my_num = "345";
int source = 8;
int destination = 2;
System.out.println("Converting the number from octal to binary: "+ base_convert (my_num, source, destination));
destination = 10;
System.out.println("Converting the number from octal to decimal : "+ base_convert (my_num, source, destination));
destination = 16;
System.out.println("Converting the number from octal to hexadecimal: "+ base_convert (my_num, source, destination));
}
}Output
Converting the number from octal to binary: 11100101 Converting the number from octal to decimal : 229 Converting the number from octal to hexadecimal: e5
A class named Demo contains a function named ‘base_convert’ is defined. This function parses the integer from source base to the destination base, converts it into a string and returns it as output. In the main function, the value for number, for source base and for different destination bases are defined. The ‘base_convert’ function is called with the number, source and destination as parameters. Relevant output is displayed.
