compiler construction - Executing a java program having input statements through another java program -


hi trying make online java compiler.

as initial poc able compile , run program having no input statements dont'd know if there input statements also.

i using runtime.getruntime().exec compile , run input java program.

sample program having input statements trying run , execute :

public class helloworld { public static void main(string[] args) {     system.out.println("hello world..................");     scanner sc = new scanner(system.in);     system.out.println("enter name");     string name = sc.nextline();     system.out.println("you entered " + name);     sc.close(); } 

}

problem when compile , run above program through code compiles , runt getting "enter name" of system.out.println("enter name"); in helloworld.java after nothing happens.
