The following code is pretty simple Java, and it looks like (to me) that the solution you have provided works just fine on my end.以下代码非常简单 Java，看起来（对我来说）您提供的解决方案对我来说效果很好。
Perhaps remember:或许还记得：
-
String.replace(String text, String replaceText) -
String.replaceAll(String regularExpression, String replaceText)
... are slightly different. ……略有不同。 The latter (the one cited in the question), accepts a "Regular-Expression" - which is compiled by the class java.lang.String Look closely at the java documentation pages for class String to see where a Regular-Expression, not a simple String is used as a parameter in "Replace-String" methods... (Google JDK Java-Docs for java.lang.String) The latter (the one cited in the question), accepts a "Regular-Expression" - which is compiled by the class java.lang.String Look closely at the java documentation pages for class String to see where a Regular-Expression, not a简单字符串用作“替换字符串”方法中的参数...（Google JDK Java-Docs for java.lang.String）
This code, for me, works just fine, However, if the first parameter to the replaceAll method were changed, and the chabge included any characters that require escaping courtesy of Reg-Ex, then the method would fail.对我来说，这段代码工作得很好，但是，如果replaceAll方法的第一个参数被更改，并且 chabge 包含任何需要由 Reg-Ex 提供的 escaping 的字符，那么该方法将失败。 For this simple case, it was fine.对于这个简单的案例，这很好。 See: replaceAll(...) and replace(...)请参阅： replaceAll(...)和replace(...)
String nonhtml = "<HTML>\n<BODY>\n<H1>Simple Test</H1>\n Hello,<BR />\n<PRE> how are you? </PRE>\n  </BODY></HTML>\n";
System.out.println(nonhtml);
System.out.println(nonhtml.replaceAll(" ", "").replaceAll(" ", ""));
Produced this output:生产了这个output：
<HTML>
<BODY>
<H1>Simple Test</H1>
Hello,<BR />
<PRE> how are you? </PRE>
  </BODY></HTML>
<HTML>
<BODY>
<H1>Simple Test</H1>
Hello,<BR />
<PRE> how are you? </PRE>
</BODY></HTML>
