String replaceAll function error

[Michael L. Zhang]

I have a small test program, but when I compile it I got an error.

    
import java.io.*;
 
public class TestReplace
{
  public static void main()
  {
    String str = "abcdef";
    String xyz = str.replaceAll("a","b");
 
    System.out.println( xyz );
  }
}
 

Can someone tell me why I got compliling error?

javac TestReplace.java

TestReplace.java:8: cannot resolve symbol
symbol : method replaceAll (java.lang.String,java.lang.String)
location: class java.lang.String
String xyz = str.replaceAll("a","b");
^

are you using a version of jave earlier than 1.4?

also, when you do get it to compile, it won't run - main() is wrong

[Michael L. Zhang]

My java version "1.3.1_14"

The issue with main(), You mean I should use

public static void main(String{} args), right?

public static void main(String[] args)

public static void main(String[] args) is the right one.
But that is not your compilation issue.

Your compilation issue is not in code. The Issue is String.replaceAll method is not in your java library.

See the documentation for 1.3

http://java.sun.com/j2se/1.3/docs/api/java/lang/String.html

replaceAll(String, String) is not defined but in jdk 1.4 and 1.5 it is present

Thanks every one!

I just joined the new company, and I assumed my java version is 1.4 or later, but it turned out it is not the case.

Will talk to company admin to upgrade the java.

[Paul Clapham]

Or if your company is not upgrading yet for some reason, then you could use the char version

String xyz = str.replace('a','b');

which does exist in Java 1.3. Note that you can only replace one char by another with this method, nothing more complex than that.
