Topics Covered :
1) What is type conversion or type casting ?
2) Types of casting?
a) implicit type casting or automatic type casting or widening type casting
b) explicit type casting or narrowing type casting
3) Error during narrowing type casting?
4)Type promotion when we do operations

Q# 1
What is type conversion or type casting ?
Type casting is when you assign a value of one primitive data type to another type.

e.g : byte b=34; int i=b

Q# 2
Types of casting?
In Java, there are two types of casting:
• Widening Casting (automatically) also known as implicit casting- converting a smaller type to a larger type size

• Narrowing Casting (manually) also known as explicit casting –
converting a larger type to a smaller size type

Q# 3
Error during narrowing type casting?
In narrowing type casting when we convert the value of the larger data type to a smaller type, you get the data loss error.


Q# 4
What is the Type promotion
When we do arithmetic operations on two same data types or different data types, java will promote the smaller data type to the larger data type.

When we perform the operations Then the value may exceed the range of operands and hence the expression value will be promoted.

a. Java automatically promotes each byte, short, or char operand to int when evaluating an expression

b. If one operand is long, float or double the whole expression is promoted to long, float, or double respectively.

int * float = float
int * long= long
int * double= double
