char initial value in Java

Question

You initialize an int variable defined within a method to have a value of 0 until you compute specific values for the int  What can one initialize char values to  char retChar      this gives an error and if I initialise to -1 it says too many characters

User · Answer

Either you initialize the variable to something

char retChar = 'x';

or you leave it automatically initialized, which is

char retChar = '\0';

an ascii 0, the same as

char retChar = (char) 0;

What can one initialize char values to?

Sounds undecided between automatic initialisation, which means, you have no influence, or explicit initialisation. But you cannot change the default.

Typically for local variables I initialize them as late as I can  It s rare that I need a  dummy  value  However  if you do  you can use any value you like - it won t make any difference  if you re sure you re going to assign a value before reading it   If you want the char equivalent of 0  it s just Unicode 0  which can be written as   char c     0     That s also the default value for an instance  or static  variable of type char
