Difference Between Type Conversion and Type Casting in Java Feature Type Conversion (Implicit) Type Casting (Explicit) Definition Automatic conversion by Java when a smaller type is assigned to a larger type. Manual conversion by the programmer when assigning a larger type to a smaller type. Who Does It? Performed automatically by the compiler. Done manually using casting operators ((type)). Data Loss No data loss (safe conversion). Possible data loss (unsafe conversion). Example int → long, float → double (smaller to larger). double → int, float → int (larger to smaller). Syntax long num = 10; (int is converted to long). int num = (int) 10.5; (double is cast to int, loses decimal part). ASCI VALUE
