How to escape $ in java?

Question

I am trying below code but getting error

String x = \"aaa XXX bbb\";
    String replace = \"XXX\";
    String y = \"xy$z\";
    String z=y.replaceAll(\"$\",          


        

Answer 1

Use replace() instead, which doesn't use regular expressions, since you don't need them at all:

String x = "aaa XXX bbb";
String replace = "XXX";
String y = "xy$z";
x = x.replace(replace, y);
System.out.println(x);

This will print aaa xy$z bbb, as expected.
