Question

用JAVA设计一个程序！ 1、用户输入不定字符串，程序打印出用户输入的字符串的长度，并且打印出字符串信息

Answer 1

你问了好几次了，
import java.util.Scanner;

public class Du {

public static void main(String[] args) {

String input = getnInputStr();

firstApplication(input);
secondApplication(input);
}

private static void secondApplication(String input) {//第二个程序

StringBuffer sb = new StringBuffer();
for(int i = 0; i < input.length(); i++){
sb.append((int)input.charAt(i));
}

System.out.println("After encrypted string is: " + sb.toString());
}

private static String getnInputStr() {
System.out.print("Please input some string: ");

Scanner scanner = new Scanner(System.in);

String str = scanner.nextLine();

return str;
}

private static void firstApplication(String str) {//第一个程序
System.out.println("The length of inputed string is: " + str.length());
System.out.println("Huiwen of inputed string is: "+ new StringBuffer(str).reverse().toString());
}
}

--------------------
Please input some string: abdsd12345xyz
The length of inputed string is: 13
Huiwen of inputed string is: zyx54321dsdba
After encrypted string is: 97981001151004950515253120121122

Answer 2

public static void main (String[] args)
{
java.uti.Scanner in = new java.util.Scanner (System.in).useDelimiter(";") ;

String ret = in.next() ;

System.out.println ("get the length is: " + ret.length() + " get the string is: "+ ret);

}

Answer 3

。。
import java.io.*;

public class Length {
public static void main(String[] args) throws IOException{
BufferedReader indata=new BufferedReader(new InputStreamReader(System.in));
String str=indata.readLine();
System.out.println("字符串信息:"+str+"\n字符串长度:"+str.length());
}
}
