如何从Java中的另一个类添加String？

Question

我想将其他（controller）类的字符串添加到＆＃34; JSON类＆＃34;我创建了但我不知道我已经在这个类中添加了一些 string [] ：
我是java的新手。你有解决我的问题的方法吗？

例如，我想在此JSON中用Table1替换我的字符串：

public class JSON {
    public String jsonfile;

    public String JSONFilter(String[] point)throws IOException {
        String count01="{\n" +
                "  \"tags\": {\n" +
                "    \"load_all\": true,\n" +
                "    \"exclude\": [\n" +
                "      \"created_by\",\n" +
                "      \"source\"\n" +
                "    ]\n" +
                "  },\n" +
                "  \"tables\": {\n" +
                "    \"Table1\": {\n" +
                "      \"fields\": [\n" +
                "        {\n" +
                "          \"type\": \"id\",\n" +
                "          \"name\": \"osm_id\"\n" +
                "        },\n" +
                "        {\n" +
                "          \"type\": \"geometry\",\n" +
                "          \"name\": \"geometry\"\n" +
                "        },\n" +
                "        {\n" +
                "          \"type\": \"hstore_tags\",\n" +
                "          \"name\": \"tags\"\n" +
                "        }\n" +
                "      ],\n" +
                "      \"type\":";

        String count02 = "\"points\",\"mapping\":{";
        String count03 = "\"amenity\":[";
        for (int i=0; i<point.length; i++){
            String b1 = "\""+point[i].toString()+"\",";
            count03+=b1;
        }
        count03 = count03.replaceAll(",$", "");
        String count04= count03+"]";
        String count06= "}}}}";
        String part_final=count01+count02+count04+count06;
        System.out.println(part_final);

    }
