class CHar
{
public static void main(String []l)
{
char j='\u0000';
System.out.println("value of char j="+j);
}
}
When I print the value of j then it prints nothing it means null value, but java dic says the default value of char is '\u0000' with which I agree, but the default value should be print. Instead of printing the default value it prints
C:\Users\Mohit-Pc\Desktop\Java Array>java CHar
value of char j=
That it is nothing means null. I'm still confused, whether I use instead of char default value, null then it generates an error:
CHar.java:5: error: incompatible types: cannot be converted to
char char j=null;

A char with value 0 is the NUL character. It is a non-printing character and does not display as anything. Traditionally, C-style strings use a NUL character to mark the end of a string.
Note that the NUL character is different from the Java null. NUL is a primitive char value, while null is a reference value. The char type cannot hold a value of null, but an object type like java.lang.Character can.
If you want to print the numeric value of a char, cast it to int first.
