    String str = "01111111";
    int radix = 2;

    // Creates an Integer object from the string
    Integer intObject = Integer.valueOf(str, radix);

    // Extracts the int value from the string
    int intValue = Integer.parseInt(str, 2);

    System.out.println("str = " + str);
    System.out.println("intObject = " + intObject);
    System.out.println("intValue = " + intValue);
