What is the difference between replace() and replaceAll() in Java?
The replace method of the String class accepts two characters and it replaces all the occurrences of oldChar in this string with newChar.
Example
import java.io.*;
public class Test {
public static void main(String args[]) {
String Str = new String("Welcome to Tutorialspoint.com");
System.out.print("Return Value :" );
System.out.println(Str.replace('o', 'T'));
System.out.print("Return Value :" );
System.out.println(Str.replace('l', 'D'));
}
}Output
Return Value :WelcTme tT TutTrialspTint.cTm Return Value :WeDcome to TutoriaDspoint.com
The replaceAll() method replaces each substring of this string that matches the given regular expression with the given replacement.
Example
import java.io.*;
public class Test {
public static void main(String args[]) {
String Str = new String("Welcome to Tutorialspoint.com");
System.out.print("Return Value :" );
System.out.println(Str.replaceAll("(.*)Tutorials(.*)", "AMROOD"));
}
}Output
Return Value :AMROOD
