Question

我在下面的代码中使用3D数组int，我正在获取数组索引超出范围的错误，下面是相同的代码：-

package array2d;

import java.util.Scanner;

public class Array3 {

    public static void main(String[] Args) {
        Scanner vee= new Scanner(System.in);
        int penilaian[][][];
        int mahasiswa[];

        for (int i = 0; i < 5; i++) {
            System.out.print("Class" + (i + 1) + " : ");
            int mhs = vee.nextInt();

            System.out.println("------------------------------------------------");
            mahasiswa = new int[mhs];

            penilaian = new int[i][mahasiswa.length][3];

            for (int j = 0; j < mahasiswa.length; j++) {
                System.out.print("Score Mid Test" + (i + 1) + " Ke -" + (j + 1) + " :");
                penilaian[i][j][0] = vee.nextInt();
                System.out.print("Score Test" + (i + 1) + " Ke -" + (j + 1) + " :");
                penilaian[i][j][1] = vee.nextInt();
                System.out.print("Score Project" + (i + 1) + " Ke -" + (j + 1) + " :");
                penilaian[i][j][2] = vee.nextInt();
                System.out.println("=======================================================================");

            }
        }
    }

}

出现以下错误：-

线程“主”中的异常java.lang.ArrayIndexOutOfBoundsException：索引0超出长度0 在array2d.TugasArray3.main（TugasArray3.java:27）得分中考1 Ke -1

Answer 1

当第一个元素的大小为penilaian = new int[i][mahasiswa.length][3];时，如果您不能为该数组分配任何值，则声明一个三维（3d）数组i=0

索引0超出长度0数组3D的范围
