Allocates a Boolean object representing the value true if the string argument is not null and is equal, ignoring case, to the string "true" .

Usage

From source file:Main.java

public static void main(String[] args) {

    Boolean blnObj1 = new Boolean(true);
    Boolean blnObj2 = new Boolean("false");
    System.out.println(blnObj1);/*w  ww  .  j  a  v  a 2s  . co m*/
    System.out.println(blnObj2);
}

From source file:Main.java

public static void main(String args[]) {
    Boolean b1 = new Boolean("TRUE");
    Boolean b2 = new Boolean("FALSE");
    System.out.println(b1.toString() + " or " + b2.toString());
    for (int j = 0; j < 16; ++j)
        System.out.print(Character.forDigit(j, 16));

    Integer i = new Integer(Integer.parseInt("ef", 16));
    Long l = new Long(Long.parseLong("abcd", 16));
    long m = l.longValue() * i.longValue();
    System.out.println(Long.toString(m, 8));
    System.out.println(Float.MIN_VALUE);
    System.out.println(Double.MAX_VALUE);
}

From source file:MainClass.java

public static void main(String[] args) {
    boolean b = true;
    Boolean b2 = new Boolean(b);
    System.out.println(b2.booleanValue());
}

From source file:WrappedClassApp.java

    for (int j = 0; j < 16; ++j)
