Type casting is the conversion from 1 data type to another.

It is of 2 types :
1. Widening
2. Narrowing

Widening

In case of widening, we convert smaller datatype like an integer to bigger data type like double.

int a = 4;
double b = a;
System.out.println(b);

Output

4.0

Narrowing

In case of narrowing we convert bigger datatype like double to smaller data type like an integer.

double c = 3.445;
int d = (int) c;
System.out.println(d);

Output:

3
