我想了解存储输入的代码行

Question

我试图了解一行的程序行不完整。然后我应该完成。该程序应该让用户输入数字，然后输出平均值，最小值和最大值。

import java.util.Locale;
import java.util.Scanner;


class Temp {
    public static void main(String[] args) {

        System.out.println("Temps\n");

        Scanner in = new Scanner(System.in);
        in.useLocale(Locale.US);

        System.out.print("numOfWeeks: ");
        int numOfWeeks = in.nextInt();
        System.out.print("Number Of Measurments Per Week: ");
        int numOfMeasurmentsPerWeek = in.nextInt();

// the input numbers from above are supposedly getting stored with the help of

// the code line bellow.

double[][] t = new double[numOfWeeks + 1][numOfMeasurmentsPerWeek + 1];

请帮助我理解代码的最后一行。
