Translating RegEx from Javascript to Java

Question

I'm writing a tool -for private use- that reads a string. The containing string is full url encoded. Normaly I use this site for decode or encode a string. So I took a look at the source code. In the source of this, I found two regexpressions:

.replace(/'/g,"%27").replace(/"/g,"%22")

and

.replace(/\+/g,  " ")

I think the first does replace all ' to %27 and " to %22. Is that right? If not, what is the pendant in Java?

At second statement, I have no idea what does it mean and do. Can some explain it and what is the pendant Java?

I'm still an absolute beginner with regexpressions, so I hope the community here can help.

Thanks.

You are right about the first statement.

As for the second statement, it is replacing plus "+" signs by spaces " " (%20).

It is written as /\+/because plus "+" is a special character and has to be escaped.

You can use the String.replaceAll method:

input.replaceAll("'", "%27").replaceAll("\"", "%22");

And

input.replaceAll("\\+", " ");
