我怎样才能使我输入的整个文本返回到 CS，而不是返回 1 个单词？

package proverka_script;

import java.util.Scanner;

public class Proverka_script {
 public static void main(String[] args) {

  String myString = null;
  Scanner num = new Scanner(System.in);
  String a = myString;
  a = num.next();
  myString = a;
  String target = "e";
  String replacement = "c";
  String newString = myString.replace(target, replacement);
  int length = newString.length();
  System.out.println(newString + " " + length);

 }
}

当我在控制台输入信息时，例如，Hello World，我只会得到“Hcllo”，而 World 会丢失。怎么样，也许值得使用StringBuffer？

    Scanner scanner = new Scanner(System.in); 

// Считали строку целяком и сразу же
// заменили первую букву на вторую
String str = scanner.nextLine().replace("e", "c");

System.out.println(str + " " + str.length());
