Java Date.parse IllegalArgument
I'm writing a test for a method that invokes Date.parse(). The code looks like this
public void someMethod(String s){
Date date = new Date();
date.setTime(Date.parse(s));
//other methods
}
in my test I did something like this
public void test(){
...
Date date = new Date();
someMethod(date.toString());
//assert statements
}
It works well on my machine, I tried it in my eclipse and IntelliJ IDEA. However, when I push it to our server for build, the test fails. It throws IllegalArgumentException. My teammate receives the same exception also. We have are using the same sdk: jdk1.7.0 and IDE eclipse and IntelliJ. The only difference is I have a jre7 installed in my machine. I also tried a simple test:
public void test(){
Date d = new Date();
String s = d.toString();
Date e = new Date();
e.setTime(Date.parse(s));
sysout(e);
}
Works well in my machine, but receives IllegalArgumentException in his machine. I cannot change the method under test so I cannot perform other conversion from string to date. Thanks
EDIT - StackTrace

Date.parse() is deprecated yet . Change the method as below and try it again .
public void someMethod(String s){
Date date = new Date();
try {
date=DateFormat.getDateInstance().parse(s);
} catch (ParseException e) {
e.printStackTrace();
}
//other methods
}

Although this may not resolve your problem, i think having a look at the DateFormatter class would be very helpful for your case.

As per the Javadocs Date.parse() was deprecated as of JDK 1.1
So you would be better of changing the following code:
Date d = new Date();
String s = d.toString();
Date e = new Date();
e.setTime(Date.parse(s));
with something like this:
Date d = new Date();
Date e = new Date();
e.setTime(d.getTime());

Date.toString() and Date.parse() are locale-dependent. As a result, it is possible for toString()'s output to not be unambiguously readable by parse(). It would be better to pass the date's timestamp, since that is just a number and is therefore unique.
