What is the Boolean class?

Rating:

The Boolean class is a wrapper class that is used to wrap true or false type primitive values in a Boolean object.

This class defines two constructors with the following signatures:

public Boolean(boolean bool_value)
public Boolean(String str)

The first form of the constructor takes a primitive type boolean as an argument, whereas the second form takes a string argument.

Most often, the second form of the constructor is used. It creates a Boolean object representing a true value if the argument passed as a string is "true", ignoring the case of the string. Otherwise, it creates a Boolean object representing a false value.
