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,然后再将字符串重新添加到一起,使其成为二进制和十进制的混合.在其他版本中,我将添加更多转换,更多分割,也可能转换为语言.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
