Java字符串是否是下划线_java – 以粗体和下划线样式将字符串写入文件

我有类WriteFile,它有方法WriteToFile,它将String写入word文档.

WriteFile data=new WriteFile("C:/test3.doc",true);

data.writeToFile(user.saxeli+" "+user.gvari+" "+user.asaki+" "+user.swori);

如何用粗体和下划线样式将String写入“test3.doc”？

这是WriteFile类：

import java.io.FileWriter;

import java.io.IOException;

import java.io.PrintWriter;

public class WriteFile {

private String path;

private boolean append=true;

public WriteFile(String path,boolean append){

this.path=path; this.append=append;

}

public void writeToFile(String text) throws IOException{

FileWriter write=new FileWriter(path,append);

PrintWriter print_line= new PrintWriter(write);

print_line.printf("%s"+"%n", text);

print_line.close();

}

}
