Hello,

For some reason, I have to use j2se 1.3.

when i use indexOf() method, for example: there are two strings :

1. Physics of electronic and optoelectronic devices

2. Microelectronics and Nanotechnology

the word i need to find out is electronic, in this case string 1 should be the result, but if using indexOf() method, both strings will be the results.

my question is: is there a way that i can only get "Physics of electronic and optoelectronic devices"? by using j2se1.3

Thank you so much for your reply,

lilyyan

hi, thanks for your prompt reply. that's a good idea.

the application currently i'm doing is user input some keywords, e.g. electronic acids disease, the progarm will get the tokens of the input string, i.e.
electronic
acids
disease
 then the program will search the token within a certian of a table

if the srting is: "electronic and optoelectronic devices", adding space to fornt and back to "electronic", will still get the result?

no, but adding a leading and trailing space to the string being search will fix that problem.

agree, but the word to be searched could be located in the front or back

As objects said, "a leading _and_ trailing space" would do the trick.

So "electronic and optoelectronic devices" would become " electronic and optoelectronic devices " before you search.
