Explanation / Answer

// Here is Your function which takes String(Password ) as an argument and check its validity. public void CheckPassword(String S){ if(S.length()90)&&((int)c < 97))||(((int)c >57)&&((int)c < 65))) { System.out.println("Invalid Password"); return ; } if(((int)c >47)&&((int)c < 58)) { k++; } } if(k < 2) { System.out.println("Invalid Password"); return ; } System.out.println("Valid Password"); } // here is Sample program using this method. import java.util.Scanner; /** * * @author Imran */ public class NewClass1 { public static void main(String args[]){ Solution s = new Solution(); } } class Solution{ public Solution(){ Scanner stdin = new Scanner(System.in); System.out.print("Enter Your Password : "); String S1 = stdin.next(); CheckPassword(S1); } public void CheckPassword(String S){ if(S.length()90)&&((int)c < 97))||(((int)c >57)&&((int)c < 65))) { System.out.println("Invalid Password"); return ; } if(((int)c >47)&&((int)c < 58)) { k++; } } if(k < 2) { System.out.println("Invalid Password"); return ; } System.out.println("Valid Password"); } }
