如何将JavaScript代码转换为一个大的Java字符串

StringBuilder sb = new StringBuilder();
sb.append("public class HelloWorld {\n");
sb.append("\tpublic static void main(String[] args) {\n");
sb.append("\t\tSystem.out.println(\"Hello, World!\");\n");
sb.append("\t}\n");
sb.append("}");
String javaCode = sb.toString();

String javaCode = String.format("public class HelloWorld {\n" +
                                "\tpublic static void main(String[] args) {\n" +
                                "\t\tSystem.out.println(\"Hello, World!\");\n" +
                                "\t}\n" +
                                "}");

String javaCode = "public class HelloWorld {\n" +
                  "\tpublic static void main(String[] args) {\n" +
                  "\t\tSystem.out.println(\"Hello, World!\");\n" +
                  "\t}\n" +
                  "}";

StringBuilder sb = new StringBuilder();
sb.append("public class HelloWorld {\n");
sb.append("\tpublic static void main(String[] args) {\n");
sb.append("\t\tSystem.out.println(\"Hello, World!\");\n");
sb.append("\t}\n");
sb.append("}");
String javaCode = sb.toString();

List<String> lines = Arrays.asList("public class HelloWorld {",
                                    "\tpublic static void main(String[] args) {",
                                    "\t\tSystem.out.println(\"Hello, World!\");",
                                    "\t}",
                                    "}");
String javaCode = String.join("\n", lines);
