Java programming class, HELP

[Watashi]

I'm currently working on an assignment, and the part I'm working on right now is the second method which should be:"The second method will be used to ask for the number of pre-requisites and perform a cumulative algorithm to create a list of pre-requisites.". I will link my program below, I have no idea why it won't run! I will link my program, aswell as the outlines for the entire assignment.

You should always post your code in the post or if it's a large project to some g it repo

 

import java.util.*;public class Paluso4 {public static final int SEATS = 50;   public static void main (String[] args) {   line(3);   String Coursestring = console1();   prereqs = console2();   }      //start loop   public static void line (int times){for(int n = 1; n <=times; n++) {      for (int t = 0; t <=54;t++) {            System.out.print("*");      }      System.out.println();      }      }    //end loop        //start console 1public static String console1 () { //variables      String Coursecode, Coursename;Scanner console = new Scanner(System.in);System.out.println("Please enter the course code: ");  Coursecode = console.nextLine();    System.out.println("Please enter the course name: ");  Coursename = console.nextLine();  String Coursestring = Coursecode + " " + Coursename;  return Coursestring;}//end console 1   //start console 2   public static void console2 (){   Int numprereq=0; String prereqcode;   System.out.println("How many pre-requisites does the course have?");numprereq = console.nextInt();for (int i = 1; i <= numprereq; i++) {   System.out.print("List pre-requisite #" + i);   String prereqcode = console.nextLine();   prereqs = prereqcode;   }   return prereqs;   }   }

public static void console2 ()
{
    int numprereq=0; 
  	String prereqcode;

    System.out.println("How many pre-requisites does the course have?");
    numprereq = console.nextInt();
    for (int i = 1; i <= numprereq; i++) {
      System.out.print("List pre-requisite #" + i);
      String prereqcode = console.nextLine();
      prereqs = prereqcode;
    }
  
    return prereqs;
}

I'm not particularly good at Java, but I think the problem lies in the "prereqs = prereqcode;" portion. The for loop keeps overwriting prereq, so only the last value is returned.

 

You could maybe use a StringBuilder object or something to append stuff to the string as it's being built. Then you can return builder.toString().
