借書(shū)系統(tǒng)，第二步輸入書(shū)籍名稱(chēng)老是錯(cuò)誤，大神求解
import java.util.Scanner;
public class TakeBook {
public static void main(String[] args) {
TakeBook test = new TakeBook();
test.select();
}
public void select() {
String[] bookName = { "Java", "python", "C++" };
System.out.println("請(qǐng)輸入對(duì)應(yīng)的命令查找書(shū)籍：\n1--按編號(hào)查找書(shū)籍\n2--按照書(shū)籍名稱(chēng)查找書(shū)籍");
Scanner input = new Scanner(System.in);
try {
int order = input.nextInt();
if (order != 1 && order != 2) {
throw new Exception();
} else {
if (order == 1) {
System.out.println("請(qǐng)輸入書(shū)籍編號(hào)：");
try {
int bookNum = input.nextInt();
if (bookNum < 1 || bookNum > bookName.length) {
throw new Exception();
} else {
System.out.println("您的書(shū)籍為：" + bookName[bookNum - 1]);
}
} catch (Exception e) {
System.out.println("請(qǐng)輸入正確的編號(hào)!\n");
throw new Exception();
}
}
}
if (order == 2) {
System.out.println("請(qǐng)輸入書(shū)籍名稱(chēng)：");
try {
String inputName = input.next();
for (int i = 0; i <= bookName.length - 1; i++) {
if (inputName.equals(bookName[i])) {
System.out.println("您的書(shū)籍為：" + bookName[i]);
} else {
throw new Exception();
}
}
} catch (Exception e) {
System.out.println("您輸入的書(shū)籍不存在，請(qǐng)重新輸入\n");
throw new Exception();
}
}
} catch (Exception e) {
System.out.println("---請(qǐng)按照提示輸入正確信息---");
select();
}
}
}

String inputName = input.next();
改成
String inputName = input.nextLine()；試試看

System.out.println("您的書(shū)籍為：" + bookName[i]);加break；跳出循環(huán)。else寫(xiě)在循環(huán)外試試?

具體是什么類(lèi)型的錯(cuò)誤？是你所輸入的書(shū)名找不到還是其他？
