Java replaceAll 带换行符

Question

当我尝试检测并替换它时，换行符\n 给我带来了一些麻烦:这很好用:

String x = "Bob was a bob \\n";
String y = x.replaceAll("was", "bob");
System.out.println(y);

但是这段代码没有给出想要的结果

String x = "Bob was a bob \\n";
String y = x.replaceAll("\n", "bob");
System.out.println(y);

Answer 1

“Bob was a bob\\n” 变成字面意思 Bob was a bob\n

输入字符串中没有要替换的换行符。您是否尝试替换换行符或转义序列 \\n？
