char assignation unicode

[el daniel]

Hi,
Can somebody explain how to assign a char variable with the simple quote (') using the unicode character \u0027 and escape character \,in order to reach the same value of c1?
char c1='\''; //OK
char c2='\u005c\u0027'; /* OK-> like c1 */
char c3='\'\u0027; //OK ->like c1 and c2
My idee was:
char c4='\\u0027'; //doesn't compile

El Daniel,
In fact, your problem is the first line :
char c1='\''; //OK
It�s not ok, because you started another literal string and didn�t finished it...

The char assignment has "too many characters in the character literal" in the assignment, char c = '\\u0027';.
As you can't do

  char c = 'ab';

it is not possible to assign

  char c = '\\u0027';

The reason is, your first escape escapes the second one. What I mean is, it would have been perfectly ok if you have said,

   char c = '\\';

And the resultant \ is not goin to be the escape part of the following u0027
So, you can see the rest of the characters are not valid for a char primitive type.
This escape business gave me headache for a while. Jose helped me out on one occasion. Here is the link if you're interested:

Yes, you cannot have two backslash together & add ur unicode, so better do what you did for c2 or what I did for c4 in the following code.

 
public class Escape{
public static void main(String[] args){
char c1='\'';
char c2='\u005c\u0027'; 
char c3='\'\u0027; 
char c4=\u0027\u005c\u0027\u0027;
System.out.println(c1 == c2);
System.out.println(c1 == c3);
System.out.println(c1 == c4);
}
} 

o/p is
true
true
true
