The function of "replaceAll" is to substitute all occurrences of a particular string in another string. Following is the syntax of this method :
public String replaceAll(String regex, String replacement)
Consider the following example for further Clarification :
import java.lang.*;
public class StringDemo {
public static void main(String[] args) {
String str1 = "!!ABC!!DEMO", str2;
String substr = "**", regex = "!!";
// prints string1
System.out.println("String = " + str1);
/* replaces each substring of this string that matches the given
regular expression with the given replacement */
str2 = str1.replaceAll(regex, substr);
System.out.println("After Replacing = " + str2);
}
}
The output of the code is as follows :
String = !!ABC!!DEMO
After Replacing = **ABC**DEMO
As you can see, all the occurrences of the substr("!!") in string1 are replaced by the regex("**").
there is no replace all in J2ME since it uses old java1.2 (AFAIK), but here is a replacement method you can use
privateString replace(String str,String pattern,String replace ){int s =0;int e =0;StringBuffer result =newStringBuffer();while((e = str.indexOf( pattern, s ))>=0){ result.append(str.substring( s, e )); result.append( replace ); s = e+pattern.length();} result.append( str.substring( s ));return result.toString();}
