用JAVA完成代码:从键盘录入一个字符串,将字符串转化为二进制数,在转化的过程中,将字符串的每一个字符单独转化 为一个二进制数,最后将所有二进制数连接起来

import java.util.Scanner;

public class StringToBinary {
    public static void main(String[] args) {
        Scanner input = new Scanner(System.in);
        System.out.print("请输入字符串：");
        String str = input.nextLine();
        StringBuilder binaryStr = new StringBuilder();
        for (int i = 0; i < str.length(); i++) {
            String charBinaryStr = Integer.toBinaryString(str.charAt(i));
            while (charBinaryStr.length() < 8) {
                charBinaryStr = "0" + charBinaryStr;
            }
            binaryStr.append(charBinaryStr);
        }
        System.out.println("转化为二进制数后为：" + binaryStr.toString());
    }
}
