    Constructors in java.lang that throw NumberFormatException
    Constructor and Description
    `Byte(String s)` Constructs a newly allocated `Byte` object that represents the `byte` value indicated by the `String` parameter.
    `Double(String s)` Constructs a newly allocated `Double` object that represents the floating-point value of type `double` represented by the string.
    `Float(String s)` Constructs a newly allocated `Float` object that represents the floating-point value of type `float` represented by the string.
    `Integer(String s)` Constructs a newly allocated `Integer` object that represents the `int` value indicated by the `String` parameter.
    `Long(String s)` Constructs a newly allocated `Long` object that represents the `long` value indicated by the `String` parameter.
    `Short(String s)` Constructs a newly allocated `Short` object that represents the `short` value indicated by the `String` parameter.
