字符串文本中的新行？

我正在将大量文本添加到字符串中。为此，我需要在文本中添加一个新行，以便在打印时，所有内容都不会处于一条直线上。如何在字符串文本中添加新行？字符串文本中的新行？

这是我的代码：

String writing = "7 Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. 8 Whoever does not love does not know God, because God is love. 9 This is how God showed his love among us: He sent his one and only Son into the world that we might live through him. 10 This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. 11 Dear friends, since God so loved us, we also ought to love one another. 12 No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us. 1 Everyone who believes that Jesus is the Christ is born of God, and everyone who loves the father loves his child as well. 2 This is how we know that we love the children of God: by loving God and carrying out his commands. 3 In fact, this is love for God: to keep his commands. And his commands are not burdensome, 4 for everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith. 5 Who is it that overcomes the world? Only the one who believes that Jesus is the Son of God."; 

    JTextArea sampleWriting = new JTextArea(); 
    sampleWriting.setText(writing); 
    sampleWriting.setFocusable(false); 

    JTextField userTypingRegion = new JTextField(); 

    dataCollectionRegion.add(sampleWriting); 
    dataCollectionRegion.add(userTypingRegion);

我试过/ n，而是在JTextArea中，写作是在一个单一的线。

使用换行字符：

String x = "line 1\nline 2";

试试这个：

StringBuilder sb = new StringBuilder("long string"); 
// adds a line separator 
sb.append(System.getProperty("line. separator")); 
sb.append("another long string"); 
// ... more lines ... 
String result = sb.toString();

上面的代码中的很大一部分是添加的行分隔符是正确的为你所在的平台（Linux操作系统，Windows等）

编辑：

现在你已经发布了代码，我可以看到这不是一个很长的字符串:)。这很简单，试试吧：

String writing = "Hello. \nWorld. \nLamp.";

对于'StringBuilder'和'line.separator' +1。 – RanRag 2012-02-20 01:33:45

对不起，我没有看到如何将这个应用到我最近刚刚提出的代码中。 – Maydayfluffy 2012-02-20 01:41:17

好，你的文字毕竟不是_that_。使用这个，然后：'String writing =“Hello。\ nWorld。\ nLamp。”;' – 2012-02-20 01:44:42
