The method of Matcher classend()The method returns the offset after the last match represented by the current object.

The sub-expression " [...]" matches the specified characters within the curly braces in the input string, as shown in the following example, to match the charactert．Here，

• We have used thecompile()The method compiles the regular expression.

• Get the Matcher object.

• matcher()Call this method on each match item.

Example

import　java.util.Scanner;
import　java.util.regex.Matcher;
import　java.util.regex.Pattern;
public　class　EndExample　{
　　　public　static　void　main(String[]　args)　{
　　　　　　Scanner　sc　=　new　Scanner(System.in);
　　　　　　System.out.println("Enter　input　text:　");
　　　　　　String　input　=　sc.nextLine();
　　　　　　String　regex　=　"[t]";
　　　　　　//Create a pattern object
　　　　　　Pattern　pattern　=　Pattern.compile(regex);
　　　　　　//Match the compiled pattern in the string
　　　　　　Matcher　matcher　=　pattern.matcher(input);
　　　　　　int　count　=0;
　　　　　　while　(matcher.find())　{
　　　　　　　　　int　end　=　matcher.end();
　　　　　　　　　System.out.println(end);
　　　　　　}
　　　}
}

Output Result

Enter　input　text:
Hello　how　are　you　welcome　to　w3codebox

Since the character 't' appears three times in the input string, you can observe three offset values (representing the position in the input string after each occurrence).
