End of the string in java

[vin Hari]

Dear experts,

please inform me how to check the end of the string in java,

as i have one string, which keeps on appending at runtime which mainly takes a file name,

so after it finishes in getting the whole string i can query otherwise it gives me wrong results

for example:

String file1=getContainerFullPath().append(getFileName()).toString();
			int pos1=file1.indexOf(".");
			String exten=file1.substring(pos1+1);

here i have to check : if i enter a file name test.abc

  if (! exten.equals("abc"))

here on splitting the file on .(dot) i have to check if this not the extensio(abc) , if not error other wise no action

so in this case i get a extenstion not equal to abc (

  if (! exten.equals("abc"))

) as the string it reads in this format like,

.a 
.ab
.abc

so till last option first two times it goes for

if (! exten.equals("abc")) 

which is not the desired

please help me how to achieve this.

Uhm, I'm not sure if I really understood the problem but are you trying to check the extension of the filename ??

In that case, use lastIndexOf(".")

Have you checked what the "file1" contains at runtime?

If you ignore the case you can also simply use the endsWith method.
