Why do we use only string in Java?why not any other data types?

Question

Very curious to learn things

Answer 1

You mean in main method?
It was implemented like that by developers.. and String array only only works well because it is used to read command line arguments which are mainly strings like file names, path names, flags,... Etc..
Anything can be stored as strings..
If you pass numbers then you can convert strings to desired types easily by String methods..
Hope it make sence...
