What is difference between implicit and explicit in java?

Answer 1

Explicit means somthing is done by the programmer

Implicit means that its done by the complier.

for example if you dont explicitly create a constructor for your class the compiler will implicitly create default one for you.

Answer 2

D_Stark please give an example using programme.

Answer 3

In general terms like these are used in type conversion

In implicit conversion the data type of the variable is converted to the highest data type (Hierachy ) present in the expression
For eg:
int a double b
c=a+b
In this the compiler will convert the value in double which is highest in expression

Explicit is forced conversion done using type cast operator for eg

int a double b
s=(int) a+b
In this the sum would be converted into int type

Hope it helps
