Question 2 plus hands-on brain Workshop

Problem 1: write a randomly generated code specifies an integer number of

 public class suiji {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc = new Scanner(System.in);

              int b;

              long a=123;

              long c=321;

              long m=456;

System.out.println ( "Please enter your desired n:");

b=sc.nextInt();

for(int i=0;i<b;i++)

System.out.println(rand(i, a, c, m));

}

public static long rand(long r,long a,long c,long m)

{

r = ( r * a + c ) % m;

return r;

}}

The following code so special:

 

Different types of parameters, different types of functions, different parameters.

Determining whether a palindrome

import java.util.Scanner;

{class Huiwen public
public static void main (String args []) {
Scanner Scanner new new SC = (the System.in);
         String = sc.nextLine STR (); // enter a string
         if (isPalindrome (str, 0) ) {
         System.out.println ( "string" + str + "palindromic sequence");
}

{the else
System.out.println ( "string" + str + "is not palindromic sequence");
}
}

public static boolean isPalindrome(String str,int index){
         System.out.println(str.charAt(0) + " " + str.charAt(str.length() - 1));
              if(str.charAt(0) == str.charAt(str.length() - 1)){
              if(str.length() > 2)

{
return isPalindrome(str.substring(index+1,str.length()-1),0);
}else return true;

}else return false;

}
}

}
