如何拆分包含空格的字符串[duplicate]

Question

public class Test
{
public static void main(String[] args)
{
    java.util.Scanner scanner = new java.util.Scanner(System.in);

    String part = "";

    System.out.println("Please enter the 2-part string to be split: ");
    part = scanner.next();

    String[] parts = part.split("-");
    String part1 = parts[0];
    String part2 = parts[1];

    System.out.print("," + part1 + "," + part2);

    scanner.close();
}

}

现在假设用户enterd

AAA-222

结果将是

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 1
    at tutorial.Test.main(test.java:17)

ps.拆分的部分应该包括空格。

Answer 1

而不是使用

part = scanner.next();

https://docs.oracle.com/javase/7/docs/api/java/util/scanner.html#next()

使用

part = scanner.nextLine();
