我有以下字符串：

mac1: 00:11:22:33:44:55
mac2: 66:77:88:99:00:11
model: PI-504
first_name: any_name
device_type: baseboard
serial_number: 668778542298745210

我想将所有值提取到一个数组中。如何用 Java 做到这一点？

public String[] getvaluesIntoStringArray(String str) {
    ....
}

您可以使用正则表达式：

private static final Pattern PATTERN = Pattern.compile(".*?:(.*)");

public static String[] getvaluesIntoStringArray(String str) {
    Matcher matcher = PATTERN.matcher(str);
    List<String> values = new ArrayList<String>();
    while (matcher.find())
        values.add(matcher.group(1).trim());
    return values.toArray(new String[values.size()]);
}

如果您想拆分新行，那么我认为应该这样做

public String[] getvaluesIntoStringArray(String str) {
    return str.split("\\r?\\n");
}

请试试

String[] result = str.split("\n");

这里代码：

public static void main(String[] args) {
        List<String> result = new ArrayList<String>();

        String str = "mac1: 00:11:22:33:44:55\n" +
                     "mac2: 66:77:88:99:00:11\n" +
                     "model: PI-504\n" +
                     "first_name: any_name\n" +
                     "device_type: baseboard\n" +
                     "serial_number: 668778542298745210";

        Pattern pattern = Pattern.compile("^.*?:(.*)$", Pattern.MULTILINE);
        Matcher matcher = pattern.matcher(str);
        boolean find = matcher.find();
        while(find) {
            result.add(matcher.group(1));
            find = matcher.find();
        }
        System.out.print(result);
    }

(?<=:\s)(.+$) 如果您的正则表达式引擎不支持后视，请使用此正则表达式 使用此正则表达式匹配项(:\s)(.+$)将在第 2 组中

ps：使用正则表达式和正则表达式MultyLine

String str = "mac1: 00:11:22:33:44:55
mac2: 66:77:88:99:00:11
model: PI-504
first_name: any_name
device_type: baseboard
serial_number: 668778542298745210";

String[] tempArr = str.split("\n");

此 tempArr 应包含以下值： mac1: 00:11:22:33:44:55 , mac2: 66:77:88:99:00:11,model: PI-504,first_name: any_name,device_type: baseboard,serial_number : 668778542298745210
