In this section, we will discuss type casting and its types with proper examples.. The following ASCII characters are used as digits: Note that since the first argument is treated as an unsigned Returns a string representation of the integer argument as an 0s. An Integer object So java programmer doesn't need to First, we have converted the double type into long data type after that long data type is converted into int type.

It takes place when: For example, the conversion between numeric data type to char or Boolean is not done automatically. Note that this method is closely related to the logarithm base 2. conversion is attempted to convert the new value to a value of In primitives, long is a larger type than int.

Parent and Child objects are two types of objects. This is why this type of conversion happens automatically. Parses the string argument as a signed decimal integer.

Hence there is no loss in data. Java has 8 primitive data types namely byte, short, int, long, float, double, char and boolean. If any operand is of a reference type, it is subjected to unboxing conversion (5.1.8).
