Decode String into Integer in Java

Submitted by donbermoy on Wednesday, December 24, 2014 - 21:53.

This tutorial will teach you how to create a program that will decode a string into integer in java. So, now let's start this tutorial! 1. Open JCreator or NetBeans and make a java program with a file name of decodeNumberSystem.java. 2. We will initialize variables in our Main, variable named decimal,octal,and hexa as String. We have initialized this variable to make this an Integer.

    String decimal = "999"; // Decimal
    String hexa = "0XFD"; // Hexa
    String octal = "067"; // Octal

3. To decode a string, we will use the decode method of the integer data type and put inside the String variables that we have declare above.

    Integer decodeDecimal = Integer.decode(decimal);
    Integer decodeHexa = Integer.decode(hexa);
    Integer decodeOctal = Integer.decode(octal);

A decode method of the integer data type decodes a String. It accepts decimal, hexadecimal, and octal numbers. 4. Lastly, display the decoded integer value of the inputted string.

    System.out.println("Decoded String [" + decimal + "] = " + decodeDecimal); 
    System.out.println("Decoded String [" + hexa + "] = " + decodeHexa);
    System.out.println("Decoded String [" + octal + "] = " + decodeOctal);

Output: output

Here's the full code of this tutorial:

public class decodeNumberSystem {
  public static void main(String[] args) {
    String decimal = "999"; // Decimal
    String hexa = "0XFD"; // Hexa
    String octal = "067"; // Octal
 
    
    Integer decodeDecimal = Integer.decode(decimal);
    Integer decodeHexa = Integer.decode(hexa);
    Integer decodeOctal = Integer.decode(octal);
    
    
    System.out.println("Decoded String [" + decimal + "] = " + decodeDecimal); 
    System.out.println("Decoded String [" + hexa + "] = " + decodeHexa);
    System.out.println("Decoded String [" + octal + "] = " + decodeOctal);
  }
}
