El método replaceAll(String) de Matcher Class se comporta como un método de agregar y reemplazar. Este método lee la string de entrada y la reemplaza con el patrón coincidente en la string del comparador.
Sintaxis:
public String replaceAll(String stringToBeReplaced)
Parámetros: este método toma un parámetro stringToBeReplaced que es la string que se reemplazará en el comparador.
Valor de retorno: este método devuelve una string con la string de destino construida reemplazando la string.
Los siguientes ejemplos ilustran el método Matcher.replaceAll():
Ejemplo 1:
// Java code to illustrate replaceAll() method
import java.util.regex.*;
public class GFG {
public static void main(String[] args)
{
// Get the regex to be checked
String regex = "(Geeks)";
// Create a pattern from regex
Pattern pattern = Pattern.compile(regex);
// Get the String to be matched
String stringToBeMatched
= "GeeksForGeeks Geeks for For Geeks Geek";
// Create a matcher for the input String
Matcher matcher
= pattern.matcher(stringToBeMatched);
System.out.println("Before Replacement: "
+ stringToBeMatched);
// Get the String to be replaced
String stringToBeReplaced = "GFG";
StringBuilder builder
= new StringBuilder();
// Replace every matched pattern
// with the target String
// using replaceAll() method
System.out.println("After Replacement: "
+ matcher
.replaceAll(stringToBeReplaced));
}
}
Before Replacement: GeeksForGeeks Geeks for For Geeks Geek After Replacement: GFGForGFG GFG for For GFG Geek
Ejemplo 2:
// Java code to illustrate replaceAll() method
import java.util.regex.*;
public class GFG {
public static void main(String[] args)
{
// Get the regex to be checked
String regex = "(FGF)";
// Create a pattern from regex
Pattern pattern = Pattern.compile(regex);
// Get the String to be matched
String stringToBeMatched
= "GFGFGFGFGFGFGFGFGFG FGF GFG GFG FGF";
// Create a matcher for the input String
Matcher matcher
= pattern.matcher(stringToBeMatched);
// Get the String to be replaced
String stringToBeReplaced = "GFG";
StringBuilder builder
= new StringBuilder();
// Replace every matched pattern
// with the target String
// using replaceAll() method
System.out.println("After Replacement: "
+ matcher
.replaceAll(stringToBeReplaced));
}
}
After Replacement: GGFGGGFGGGFGGGFGGFG GFG GFG GFG GFG
