How to set value using properties file ?

Question

I did it set and get but when I set a key other key is deleted.

***Properties File***
name=pedro
number=2

I used this method....

prop.setProperty ("name", "test");

It write very well but number key is deleted.

I need to set all keys:

prop.setProperty ("name", "test");
prop.setProperty ("number", "123");

I wanna set only one key.
