Why do we use " " to define the can't we use ' ' and if no then please let me the reason behind that.

Like why we write String var = "hello" And why String var = 'hello' not.

Because char and String are two different data types, and how else is Java supposed to know whether you want a character or string of length 1? For example, given the methods : public void foo(String s) { } public void foo(char c) { } And the call : foo('a'); If Strings would be made using single quotes, how would Java know that its a char or a String?
