RE: What is the argument type of a program's main() method
you write public static void main(String args[])

so the argument type isstring and whatever input you give as

java abs "asd" 1

then all the 3 arguments are stored int he corresponding string format in the args array and if you write
 
for(int i=0;i<args.length;i++)
{  System.out.println(args[i]);}
 the it prints:
abs
"asd"
1
