我正在制作一个新的转换软件来隐藏消息(为了好玩)。我做了一个二进制和十进制转换类,我的想法是,用户输入字符串,它将所有转换为二进制格式。然后将它分成两半,将一半转换为十进制,然后再次将字符串加在一起,使其成为二进制和十进制的混合体。在其他版本中,我将添加更多转换、更多拆分,并且可能也会转换为语言。我需要将字符串分成两半。到目前为止,这是我的代码::
public ray() {
Scanner in = new Scanner(System.in);
while (true) {
System.out.println("Please input the text you wish to encode!");
System.out.println("Type '#' to quit the Software.");
String s1 = in.nextLine();
if ("#".equalsIgnoreCase(s1)) {
System.out.println("Goodbye, hope you enjoyed RAYConversion v1.0 Alpha.");
// close software
}
// convert all to binary
binary Binary = new binary();
//what i need to do is split stirng s1 in half, make it into different strings. Then I will convert
//the two strings to binary and decimal. I made a converter for that.
}
}
最佳答案
final int mid = s1.length() / 2; //get the middle of the String
String[] parts = {s1.substring(0, mid),s1.substring(mid)};
System.out.println(parts[0]); //first part
System.out.println(parts[1]); //second part
