Java输出到文本文件？

试试这个 ：

public void text() {        try { PrintWriter output = new PrintWriter("test.txt"); output.println(data[0]); for (int i = 0; i < data.length; i++) {     if (i != (data.length - 1)) {         output.printf("%d, ", data[i]);     } else {         output.printf("%d", data[i]);     }     output.flush(); }        } catch (Exception ex) {        }    }
