Java replaceAll with newline symbol

Question

换行符号\n当我尝试检测并替换它时会给我带来一些麻烦: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理想的结果

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

Answer 1

"Bob was a bob \\n" 从字面上看 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？
