【问题描述】：
我讨厌数组
所以我一直在进行一些编码，但我遇到了一个我似乎无法修复的错误（超出范围异常）。我相信我在说'array1[counter2][counter] = input2.nextLine();'是问题，但我不知道出了什么问题！求助，我受不了这些越界异常
该程序的理念是一个在线电话簿，您可以在其中添加联系人、查看他们并通过他们的名字、姓氏和电话号码进行搜索。
这是我正在使用的代码：
import java.util.Scanner;
import java.awt.*;
public class testMattWalker {
//
public static void main (String[] args){
//Declare all your variables here. Make sure to provide a comment explaining the purpose of each variable
Scanner input = new Scanner(System.in);
Scanner input2 = new Scanner(System.in);
Scanner input3 = new Scanner(System.in);
Scanner input4 = new Scanner(System.in);
int counter = 0;
int counter2 = 0;
boolean go = true;
//Temp VAriables for entry
String firstNameOfEntry = "";
String lastNameOfEntry = "";
String personPhoneNumber = "";
//
//create array
String [][] array1 = new String[5][3];
while (go) {
String choice = "";
System.err.println("\n\n\n\n\n\n\n\n\nDIDGITAL PHONE BOOK 2013");
System.out.println("1- Create phone book\n2- Display phone book\n3- Find person(s) by last name\n4- Find person(s) by first name\n5- Find person(s) by phone number\n6- Exit application");
choice = input.nextLine();
if (choice.equals("1") && counter2 != 6) {
System.err.println("\n\n\n\n\nPHONE BOOK ENTRY CREATOR:");
System.out.println("Please enter the first name of the person you wish to enter: ");
array1[counter2][counter] = input2.nextLine();
counter++;
System.out.println("Please enter the last name of the person you wish to enter: ");
array1[counter2][counter] = input3.nextLine();
counter++;
System.out.println("Please enter the phone number of this person: example:9057773344");
array1[counter2][counter] = input4.nextLine();
counter++;
counter2++;
}else if (choice.equals("2")) {
}else if (choice.equals("3")) {
}else if (choice.equals("4")) {
}else if (choice.equals("5")) {
}else if (choice.equals("6")) {
}
}
}// end of main
}// end of class
我知道这还没有完成，但我是那种喜欢在继续之前解决所有问题的人，所以任何帮助都将不胜感激！ （：
