本文提供了一个Java方法，用于从文件中读取字符串并将其追加到StringBuilder中，最后返回构建的字符串。同时展示了如何将Java代码转换为特定文件，包括文件路径和编码设置。

private String readStringFromFile(File file) {
BufferedReader br = null;
InputStreamReader isr = null;
StringBuilder builder = new StringBuilder();
try {

isr = new InputStreamReader(new FileInputStream(file), "UTF-8");
br = new BufferedReader(isr);

String line = null;
while((line = br.readLine()) != null) {
builder.append(line);
}

return builder.toString();
} catch(Exception e) {
return null;
} finally {

if(isr != null) {
try {
isr.close();
}catch(Exception e) {}
}

if(br != null) {
try {
br.close();
}catch(Exception e) {}
}
}
}

private void writeJavaClassFile(final String code) {
try {
FileOutputStream os = new java.io.FileOutputStream(javaClassFile);
BufferedWriter bw = new BufferedWriter(new java.io.OutputStreamWriter(os, "UTF-8"));
bw.write(code);
bw.close();
os.close();
} catch (IOException e) {
}
}
