有沒有辦法通過創(chuàng)建一個(gè)等于該字符的新字符串變量來解決這個(gè)問題import java.util.Scanner;public class mean_and_scary {    public static void main(String args[]) {        Scanner scanner = new Scanner(System.in);        System.out.println("Enter Text:");        String text = scanner.nextLine();        char leftchar = scanner.next().charAt(0);        char rightchar = scanner.next().charAt(0);        char removechar = scanner.next().charAt(0);        int width = scanner.nextInt();        text = text.replace(removechar, ""); // at this point        text = text.toUpperCase();        System.out.println(text);        scanner.close();    }}
