formatting..

[sireesha]

i saw this code in a book.

Code:

import java.util.*;
public class test4
{
public static void main(String args[])
 {
Calendar c=Calendar.getInstance();
System.out.format("%tB %td,%tY%n",c,c,c);
System.out.format("%tl:%tM %tp%n",c,c,c);
System.out.format("%tD%n",c);
 }
}

but when i compile this i got some errors.
like..

Code:

test4.java:12: cannot resolve symbol
symbol  : method format (java.lang.String,java.util.Calendar,java.util.Calendar,
java.util.Calendar)
location: class java.io.PrintStream
System.out.format("%tB %td,%tY%n",c,c,c);
          ^
test4.java:13: cannot resolve symbol
symbol  : method format (java.lang.String,java.util.Calendar,java.util.Calendar,
java.util.Calendar)
location: class java.io.PrintStream
System.out.format("%tl:%tM %tp%n",c,c,c);
          ^
test4.java:14: cannot resolve symbol
symbol  : method format (java.lang.String,java.util.Calendar)
location: class java.io.PrintStream
System.out.format("%tD%n",c);
          ^
3 errors

what is wrong with this code ?
is it necessary to import any other packages ?
please tell me....

Hello sireesha,

You are probably using an older version of Java. Format is a relatively recent addition to PrintStream. (meaning a recent addition to System.out)

Hi,
I installed jdk6 in my pc.
am i using correct version ?
what i have to install ?
please tell me.

Hi Sireesha,

System.out.format was introduced in J2SE 5.0. If you have a jdk later than that, it should work.

If you are facing problems, try replacing the format with printf. For most practical purposes System.out.format and System.out.printf are the same.

Are you sure that you are using java 6? Meaning do you have the right java folder in your PATH?
Do:

Code:

java -version

It tells you the version that you are running.

I tried it.Result is

Code:

E:\WINDOWS\java>java -version
java version "1.6.0_03"
Java(TM) SE Runtime Environment (build 1.6.0_03-b05)
Java HotSpot(TM) Client VM (build 1.6.0_03-b05, mixed mode)

now what i have to do.
is this the correct version ?

please see previous posts in this thread..give me advise..
thankq verymuch

sireesha, since you are having problems compiling, post the output of

Code:

javac -version

which is different from above. java is the command for running the application while javac is used for compiling your classes. By default, some systems (like my Ubuntu system), contains symlinks to the 1.4 version for the javac command, which obviously can present problems. If this is the case for you, you would simply need to make the link for the javac command to your more updated jvm, in your case 1.6.

hi
i tried javac -version
but the output is
javac: invalid flag: -version

now what i have to do ?
please tell me,
thankq

Code:

C:\>javac -version
javac 1.6.0_02

C:\>

Strange .. !!

All Ubuntu users who upgrade to Java 6 need to check their javac compiler link as it is still pointing to the Java 1.4 if they didn't install the Java source. I noticed this when I did a check on my system and was having a problem compiling a 'System.out.format()' and couldn't figure out why I was getting the following error;

Format.java:33: cannot resolve symbol
symbol : method format (java.lang.String,java.util.Calendar)
location: class java.io.PrintStream
System.out.format("Local time: %tT", Calendar.getInstance());

Check your links in Ubuntu;

schmidty@laptop:~/java_work$ ls -alh /etc/alternatives/javac
lrwxrwxrwx 1 root root 27 2007-12-20 18:17 /etc/alternatives/javac -> /usr/lib/j2se/1.4/bin/javac
schmidty@laptop:~/java_work$ ls -alh /etc/alternatives/java
lrwxrwxrwx 1 root root 36 2007-12-20 18:22 /etc/alternatives/java -> /usr/lib/jvm/java-6-sun/jre/bin/java
schmidty@laptop:~/java_work$ ls -alh /etc/alternatives/javac
lrwxrwxrwx 1 root root 33 2008-01-06 22:42 /etc/alternatives/javac -> /usr/lib/jvm/java-6-sun/bin/javac
schmidty@laptop:~/java_work$ ls -alh /etc/alternatives/java
lrwxrwxrwx 1 root root 36 2007-12-20 18:22 /etc/alternatives/java -> /usr/lib/jvm/java-6-sun/jre/bin/java

Again, the solution would be to install the source for Java6 in Ubuntu.
