Thread: how to reuse method returned string ??

I am trying to develop a hangman game. the code is right here.

import java.util.Vector;
 
public class SearchChar {
 
	public static void main(String args[]){
 
		String main= new String("zeeshannabeel");
		String search= new String("e");
 
		String s= printdash(main);
		char[] prestring= s.toCharArray();
		Vector<Integer> vectorarray= getindex(main, search);
 
		char[] searcharray= search.toCharArray();
		char[] strings= guess(prestring,searcharray,vectorarray);
		System.out.println(strings);
 
	}
 
	/* --- To print dash first time --- */
	public static String printdash(String main){
		String dash= new String();
		for(int z=0; z<main.length(); z++){
			dash= dash.concat("-");
			}
		System.out.println(dash);
		return dash;
 
		}
 
	/* --- To find the IndexOf search string in Main string --- */
	public static Vector<Integer> getindex(String main, String search){
		Vector<Integer> varray= new Vector<Integer>();
 
		for(int i=0; i<=main.lastIndexOf(search); i++){
			varray.addElement(main.indexOf(search, i));
			i= main.indexOf(search, i);
		}
		/* --- To print indexOf Search string in Main string --- */ 
		for(int a=0; a<varray.size(); a++){
			System.out.println(varray.get(a));	
		}
		return varray;
	}
 
	/*------ To insert Search character in String --- */
	public static char[] guess(char[]pre_string, char[]guess_string, Vector<Integer> vectorarray){
		int j=0;
		while(j<vectorarray.size()){
			int k=vectorarray.elementAt(j);
			for(int i=0; i<guess_string.length; i++){
				pre_string[k]= guess_string[i];				
				k++;
			}
			j++;
 
		}
			return pre_string;
		}
}
