Thread: default Value of char

im writing an exercise code, where i need to deal with a character sequence using a char[] array,
i need to tell the computer to check for a default value of an index of that char[] array

if (value in the index of this char[] array is default or offset) {

// do something
}

given that , 0 is default of integers, 0.0 for doubles, "" empty string with Strings, how about character?

 char someChar = '',

if a single quotation is a compile error? a closed character literal, if i put some space, its a white space character..
how can i assign an offset value for a character variable?

String isn't primitive the default value for a String reference is null - the same as all other references.

Primitive types only hold valid values. How do you distinguish between valid data of 0 in an int and never-been-assigned? Perhaps you ought to consider using the 'wrapper' classes java.lang.Boolean, java.lang.Character etc?

String isn't primitive the default value for a String reference is null

thank you for correcting my statement, objects/references has a 'null' as a default value,

java.lang.Character

ahh, so by using a wrapper class's object, i can compare a value between a 'null' and a valid one... thanks thanks
