我正在嘗試將控制臺輸出導(dǎo)出到文本文件。此輸出也來自串行端口。但是，我做不到，它只打印一行。誰能幫我？我寫的代碼如下。 String input = new String(buffer, 0, len); // convert buffer to string myLinkedList = removeComma(input); //format string data String[] array = myLinkedList.toArray(new String[myLinkedList.size()]); // put array the formatted data PrintStream fileOut = new PrintStream(new FileOutputStream("C:\\Users\\khas\\Desktop\\output.txt")); System.setOut(fileOut); for (int i = 0; i < array.length; i++) { System.out.print(array[i] + " "); } System.out.println("");

因?yàn)槟闶褂?code>System.out.print(array[i] + " ");，
你可以把它改成 System.out.println(array[i] + " ");

您需要一個(gè)流同時(shí)寫入控制臺和文件，您可以通過使用commons-io 的TeeOutputStream一部分將流到控制臺和流到文件作為參數(shù)來創(chuàng)建此流
PrintStream original = System.out; //the stream of the console
FileOutputStream fileOut = new
FileOutputStream("C:\\Users\\khas\\Desktop\\output.txt"); //the stream of your file
OutputStream outputtee = new TeeOutputStream(originalOut, fileOut); //join both streams
PrintStream printTee = new PrintStream(outputTee);
System.setOut(printTee); // and set as the default out
