Decodes a String into an Integer .

Usage

From source file:Main.java

public static void main(String[] args) {

    System.out.println(Integer.decode("010"));// octal numbers
    System.out.println(Integer.decode("0XA"));// hexadecimal numbers
    System.out.println(Integer.decode("-0XA"));// minus hexadecimal numbers
    System.out.println(Integer.decode("-#A"));// minus hexadecimal numbers
}

From source file:Main.java

public static void main(String[] args) {
    String decimal = "10"; // Decimal
    String hexa = "0XFF"; // Hexa
    String octal = "077"; // Octal

    Integer number = Integer.decode(decimal);
    System.out.println("String [" + decimal + "] = " + number);

    number = Integer.decode(hexa);
    System.out.println("String [" + hexa + "] = " + number);

    number = Integer.decode(octal);
    System.out.println("String [" + octal + "] = " + number);
}
