无法使用 PrintWriter 创建多个文件

Question

So I'm writing a really basic program for school that first asks me to create multiple text files.

PrintWriter pw = new PrintWriter( "lastname//finance.txt, lastname//taxrecords.txt" );

But when I try and run the program it doesn't even create one of the files and says something is wrong with the bolded parts. When I try and use PrintWriter twice it says the variable is already defined.

Answer 1

you need to use different instances of PrintWriter objects. one instance for each file you want to write in.

PrintWriter firstFileWriter = new PrintWriter("lastname//finance.txt");
PrintWriter secondFileWriter = new PrintWriter("lastname//taxrecords.txt");

then you could use firstFileWriter.write("something"); to write in your first file, and secondFileWriter.write("something else"); to write in second one
