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

As you will see in linked discussion there is no need for initializing char with special character as it's done for us and is represented by '\u0000' character code.

So if we want simply to check if specified char was initialized just write:

if(charVariable != '\u0000'){
 actionsOnInitializedCharacter();
}

Link to question: what's the default value of char?

Perhaps 0 or   u0000  would do

i would just do   char x   0    Which will give you an empty value of character

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

User · Answer

you can initialize it to     instead   Also  the reason that you received an error -1 being too many characters is because it is treating  -  and 1 as separate
