java - 用 "Enter"分割字符串

Question

我有代码将一个字符串拆分为 3 个字符串，然后打印它们。我希望每个人都被相当于“Enter”的人分开。这是代码:

String accval = text;
        try {
            PrintWriter writer = new PrintWriter(new BufferedWriter(
                    new FileWriter("sdcard/YS Data/Accelerometer.html",
                            true)));
            String[] tempArr = accval.split("\\s+");
            String x = tempArr[0] + "_"; //I want the enter to be where the underlines are:
            String y = tempArr[1] + "_";
            String z = tempArr[2] + "_";

            for (String a : tempArr) {
                writer.println("<h3 style=padding-left:20px;>" + x + y
                        + z + "</h3><br>");
            }

            writer.flush();
            writer.close();

        } catch (IOException e) {
            // put notification here later!!!
            e.printStackTrace();
        }

这个输出:

x=-0.125_y=0.9375_z=0.375
x=-0.125_y=0.9375_z=0.375

字符串之间用下划线分隔。

但是，我希望它看起来像这样:

x=-0.125 
y=0.9375 
z=0.375
x=-0.125 
y=0.9375 
z=0.375

感谢您的帮助。

编辑:

我已经在下面的代码中实现了@Julius 的答案，打印出我想要的方式:

代码:

 String accval = text;
        try {
            PrintWriter writer = new PrintWriter(new BufferedWriter(
                    new FileWriter("sdcard/YS Data/Accelerometer.html",
                            true)));
            String[] tempArr = accval.split("\\s+");
            String x = tempArr[0];
            String y = tempArr[1];
            String z = tempArr[2];

            for (String a : tempArr) {
                writer.println("<h3 style=padding-left:20px;>" + x + "<br>" + y + <br>
                        + z + "</h3><br>");
            }

            writer.flush();
            writer.close();

        } catch (IOException e) {
            // put notification here later!!!
            e.printStackTrace();
        }

打印:

x=0.25
y=125
z=1.23

x=0.125
y=725
z=0.935

如果你想在浏览器中显示返回行，这是要走的路:

writer.println("<h3 style=padding-left:20px;>" + x + "<br/>" + y + "<br/>" + z + "<br/></h3>");
