| /* Example of using type cast in java */ | |
| class TypeCast{ | |
| public static void main(String args[]){ | |
| int myInt = 123; | |
| double myDouble = 123.0; | |
| String myStr = "123"; | |
| String txtStr = "Hello, World!"; | |
| /* It doesn't give actual value because result will be integer and it doesn't include decimal numbers */ | |
| System.out.println("myInt/5 gives :- " + (myInt / 5)); | |
| // Its modulus gives remainder as result | |
| System.out.println("myInt%5 gives :- " + (myInt % 5)); | |
| /* It gives actual answer because double is decimal type and result is double */ | |
| System.out.println("myDouble/5 gives :- " + (myDouble / 5)); | |
| // Another type-cast by forcing double math | |
| System.out.println("myInt/5.0 gives :- " + (myInt / 5.0)); | |
| // Attemp to convert string to int but it gives error | |
| //System.out.println("myStr to int :- " + (int)myStr); | |
| /* java has a Integer class which has a method parseInt it to convert string to integer */ | |
| System.out.println("Converting string to int :- " + Integer.parseInt(myStr)); | |
| // converting a text string to int gives runtime error | |
| //System.out.println("Converting text string to int :- " + Integer.parseInt(txtStr)); | |
