e429. Quintessential Regular Expression Search and Replace Program
This program finds all matches to a regular expression pattern and
replaces them with another string.
If the replacement is not a constant string, see
e430 Searching and Replacing with Nonconstant Values Using a Regular Expression.
import java.util.regex.*;
public class BasicReplace {
public static void main(String[] args) {
CharSequence inputStr = "a b c a b c";
String patternStr = "a";
String replacementStr = "x";
// Compile regular expression
Pattern pattern = Pattern.compile(patternStr);
// Replace all occurrences of pattern in input
Matcher matcher = pattern.matcher(inputStr);
String output = matcher.replaceAll(replacementStr);
// x b c x b c
}
}
