需要建议以更好的方式处理这个问题吗？

我的数据存储为 TAX|CHURCH, Texas, San Antonia, 250.00 | SCHOOL, NEVADA, Park-SCHOOL, 122.1 其中 TAX,CHURCH, SCHOOL 是我不感兴趣但它们的价值的代码。

if (input != null && !"NOTFOUND".equalsIgnoreCase(input)) {
    String[] list_str = input.split("\\|");
    int list_length = list_str.length;
    int i;

    for (String asset : list_str) {
        System.out.println(" asset : " + asset);
        if (asset.contains("TAX")) {
            /* get values for "TAX" */
            /* replace "TAX" from values */
        }

        if (asset.contains("CHURCH")) {
            input = input.replaceFirst("CHURCH", "");
        }

        if (asset.contains("SCHOOL")) {
            input = input.replaceAll("SCHOOL", "");
        }
    }
}

System.out.println(" input : " + input); /* final input */

输入条件：

我的输入字符串可能看起来像 =
"TAX|CHURCH, Texas, San Antonia, 250.00 | SCHOOL, NEVADA, Park-SCHOOL, 122.1"
或"CHURCH, Texas, San Antonia, 250.00 | SCHOOL, NEVADA, Park-SCHOOL, 122.1"
或 "TAX|CHURCH, Texas, San Antonia, 250.00"
或 "CHURCH, Texas, San Antonia, 250.00"

我得到的最终输入是“ ,Texas, San Antonia, 250.00 | , NEVADA, Park-, 122.1 ”，但我希望我的最终字符串是

输入=“德克萨斯州，圣安东尼亚，250.00，内华达州，帕克学校，122.1 ”

如果输入格式保证是您提到的格式之一，则以下代码将起作用：

public class TestClass {

public static void main(String[] args) {
    String input = "TAX|CHURCH, Texas, San Antonia, 250.00 | SCHOOL, NEVADA, Park-SCHOOL, 122.1";
    String[] parts = input.split(" \\| ");
    String result = parts[0].split("CHURCH, ")[1];

    if (parts.length > 1) {
        result += ", " + parts[1].substring(8); 
    }

    System.out.println(result);
}

}

这会将整个表达式分成两部分，使用正则表达式检查字符串|，使用单独的正则表达式获取CHURCH,第一部分之外的所有内容，如果存在表达式的第二部分，则使用硬编码索引来获取您需要的子字符串，因为第二部分总是以SCHOOL,

我建议阅读在这种情况下非常有用的正则表达式。

我只是添加这样的空格：

    String input = "CHURCH, Texas, San Antonia, 250.00 | SCHOOL, NEVADA, Park-SCHOOL, 122.1";
    String i = "";
    if (input != null && !"NOTFOUND".equalsIgnoreCase(input)) {

        String[] list_str = input.split(" \\| ");

        for (String asset : list_str) {
            System.out.println(asset);
            i = i + asset+" ";
            if (asset.contains("TAX")) {
                /* get values for "TAX" */
                /* replace "TAX" from values */
            }

            if (input.contains("CHURCH,")) {
                i =  i.replaceFirst("CHURCH,", "");
            }

            if (input.contains(" SCHOOL,")) {
                i =  i.replaceAll(" SCHOOL,", "");
            }


        }

    }
    System.out.println(" input : " + i); /* final input */

试试这个

String input = "CHURCH, Texas, San Antonia, 250.00 | SCHOOL, NEVADA, Park-SCHOOL, 122.1";

if (input != null && !"NOTFOUND".equalsIgnoreCase(input)) {
    String[] list_str = input.split("\\|");

    for (String asset : list_str) {
        System.out.println(" asset : " + asset);
        if (asset.contains("TAX")) {
            /* get values for "TAX" */
        /* replace "TAX" from values */
        }

        if (asset.contains("CHURCH")) {
            input = input.replaceFirst("CHURCH,", "");
        }

        if (asset.contains("SCHOOL")) {
            input = input.replaceFirst("SCHOOL", "");
        }
    }
    input = input.replaceAll(" \\| ", "");
}

System.out.println(" input : " + input); /* final input */
