SimpleDateFormat does not handle leading blanks for HHmmss format
Hi,
I came accross a piece of code :
import java.util.*;
import java.io.*;
import java.text.*;
public class SDFTest{
public static void main(String[] args) {
try{
System.out.println("\"102030\" --> " + getTime("102030"));
System.out.println("\"002030\" --> " + getTime("002030"));
System.out.println("\" 12030\" --> " + getTime(" 12030"));
System.out.println("\" 2030\" --> " + getTime(" 2030"));
System.out.println("\"\" --> " + getTime(""));
}catch(Exception e){
e.printStackTrace();
}
}
private static String getTime(String time_str){
SimpleDateFormat sdf = new SimpleDateFormat("HHmmss", new Locale("ja", ""));
ParsePosition pp = new ParsePosition(0);
sdf.setLenient(false);
Date date = sdf.parse(time_str, pp);
return sdf.format(date);
}
}
The output from this code using java 1.4 is as follows
"102030" --> 102030
"002030" --> 002030
" 12030" --> 012030
java.lang.NullPointerException
at java.util.Calendar.setTime(Calendar.java:1032)
at java.text.SimpleDateFormat.format(SimpleDateFormat.java:785)
at java.text.SimpleDateFormat.format(SimpleDateFormat.java:778)
at java.text.DateFormat.format(DateFormat.java:314)
at testSimpleDateFormat.getTime(testSimpleDateFormat.java:23)
at testSimpleDateFormat.main(testSimpleDateFormat.java:11)
So, with a string like " 2030", I get a null pointer exception. Is the string format incorrect for the pattern "HHmmss" ?
