printing default value of char

[Loveleen Saroya]

 
class x
{
static boolean b;
    static char c;
    static String str;
    static int i;
    static float f;
public static void main(String[] args) 
{
System.out.println(c);//1
System.out.println(b);
System.out.println(str);
        System.out.println(i);
        System.out.println(f);
     }
}
 

why it doesnt print anything?? but if i put the line //1 in the last then it prints y???

hi,
What i came to find out that its printing the default value of char
when i run the code with this

System.out.println(c);//this prints space which u are not able to identify
System.out.println(b);//this prints false
System.out.println(str);//this prints null
System.out.println(i);//this pritns 0
System.out.println(f);//this prints 0.0

i got the following output

false
null
0
0.0

System.out.println(b);//this prints false
System.out.println(str);//this prints null
System.out.println(i);//this pritns 0
System.out.println(f);//this prints 0.0
System.out.println(c);//this prints space which u are not able to identify

i got the following output
false
null
0
0.0



the difference is that it prints the space which remains unidentified,in the first code before 'false' and in the second after '0.0'

Hi,

It is not printing anythin may be because the default value of char that is '\u0000' is not printable.

but if i put the line //1 in the last then it prints y???

for me it did not printed anything both in the last as well as in the first
it just prints a single space at both the places that's it.

I modified the code so that we can see wat the output is

 
class x
{
static boolean b;
    static char c;
    static String str;
    static int i;
    static float f;
public static void main(String[] args) 
{
System.out.println("."+c+".");//1
System.out.println(b);
System.out.println(str);
        System.out.println(i);
        System.out.println(f);
System.out.println("."+c+".");//1
     }
}
 

output:
. .
false
null
0
0.0
. .

Various output "devices" print the character with value 0 in different ways. Some print nothing, some print some "funny" symbol indicating that they can't print a proper character. "Devices" include things like Windows command console windows and xterm windows as well as laser printers, teletypes, matrix printers, etc.

hi Loveleen ..

iam using Jdev.when i executed the code its printing a symbol which represents like this []...in the first as well last instead of blank space as suggesting by our frnds .

why so??

thanks

this is the reason you are getting symbol.
