Java 中解析字符串有哪些不同的方法 [关闭]

在Java中，解析字符串是非常常见的任务之一。有多种不同的方法可以用来解析字符串，每种方法都有其适用的场景和优势。下面将介绍几种常用的字符串解析方法，并提供相应的案例代码。

java
String str = "Hello,World,Java";
String[] parts = str.split(",");
for (String part : parts) {
    System.out.println(part);
}

java
String str = "Java123Programming456";
Pattern pattern = Pattern.compile("\\d+");
Matcher matcher = pattern.matcher(str);
while (matcher.find()) {
    System.out.println(matcher.group());
}

java
String str = "Java Programming Language";
StringTokenizer tokenizer = new StringTokenizer(str);
while (tokenizer.hasMoreTokens()) {
    System.out.println(tokenizer.nextToken());
}

java
String str = "Java 123 Programming";
Scanner scanner = new Scanner(str);
while (scanner.hasNext()) {
    if (scanner.hasNextInt()) {
        System.out.println(scanner.nextInt());
    } else {
        System.out.println(scanner.next());
    }
}
