在java中向对象数组添加更多变量

我的一个项目搞得一团糟。我必须创建一个对象数组。我制作了一个数组,但它只有一个字段“myMonths”,表示项目的时间长度。 在我的主要方法中:

case 1:

    int n = 1;    //int n = number of projects
    Scanner sc = new Scanner(System.in);

    //myMonths = new int[amount];

    System.out.println("** Only projects with a duration between 2 and 12 months can be included **");
    System.out.println("What was the duration of your projects in months?");

    for(int i=0; i<1; i++){
        int a = sc.nextInt();

        //display error message
        if((a < 2) || (a > 12)){
            System.out.println(" Please enter an amount between 2 and 12 months. ");
        }

        //add to the array
        else{
            myMonths[index++] = a;
        }
    }

    calc.setMyMonths(myMonths); //creating the object
    break;

在我的课堂上,单独归档:

public class MenuTestClass{

private int myMonths[];
private double average; //store average value of numbers
private boolean averageCanBeCalculated;
private int max; // store max number from array. to be calculated

public MenuTestClass(){
    myMonths = new int[5];
    }

 public MenuTestClass(int[] myMonths){
   this.myMonths = myMonths;
   }
 public void setMyMonths(int[] values){ //declare setter method
   myMonths = values;
   }

我应该再加两个字段,两个字符串。有没有一种方法可以将更多字段/属性添加到此数组中,并在1个索引下同时查看它们?例如,在[0]projectName、projectManager、myMonths ie(字符串、字符串、整数)。 任何建议都很好,我对OOP感到非常困惑。提前谢谢!
