Type Casting In Oop Javatpoint Code Example

Example 1: java type casting

// You can typecast to convert a variable of one data type to another. // Wide Casting converts small data types to larger ones. // Narrow Casting converts large data types to smaller ones. // Java can automatically Wide Cast. // Java will throw an error when trying to automatically Narrow Cast. // This is because data is often lost when Narrow Casting. // Narrow Casting must be done manually.  //Wide Cast: int SomeNumber = 5; double WideCastedNumber = (double)SomeNumber;  //Narrow Cast: double SomeNumber = 5.39; int NarrowCastedNumber = (int)SomeNumber; //Note: The data that holds the decimal places will be lost!

Example 2: cast java

JAVA: Example of cast:  int SomeNumber = 5; //int  double WideCastedNumber = (double)SomeNumber; //from int to double  double myDouble = 9.78; int myInt = (int) myDouble; // from double to int
