有没有一种简单的方法可以将多行文本连接成一个字符串而无需不断添加换行符?

问题描述

所以我基本上需要这样做:

So I essentially need to do this:

String text = "line1\n";
text += "line2\n";
text += "line3\n";
useString( text );

涉及更多，但这是基本思想.有没有什么可以让我做更多类似的事情?

There is more involved, but that's the basic idea. Is there anything out there that might let me do something more along the lines of this though?

DesiredStringThinger text = new DesiredStringThinger();
text.append( "line1" );
text.append( "line2" );
text.append( "line3" );
useString( text.toString() );

显然，它不需要完全那样工作，但我想我明白了基本点.总是可以选择编写一个自己处理文本的循环，但是如果有一个标准的 Java 类已经在做这样的事情，而不是我需要在应用程序之间携带一个类，这样我就可以了，那就太好了做一些微不足道的事情.

Obviously, it does not need to work exactly like that, but I think I get the basic point across. There is always the option of writing a loop which processes the text myself, but it would be nice if there is a standard Java class out there that already does something like this rather than me needing to carry a class around between applications just so I can do something so trivial.

谢谢！

推荐答案

您可以使用 StringWriter 包裹在 PrintWriter:

You can use a StringWriter wrapped in a PrintWriter:

StringWriter stringWriter = new StringWriter();
PrintWriter writer = new PrintWriter(stringWriter, true);
writer.println("line1");
writer.println("line2");
writer.println("line3");
useString(stringWriter.toString());
