(In a case insensitive way) The last line after inputing all names should be " ". / /Problem: my program seems to be logically correct but the compiler is ignoring the else statement & i dont understand why.../ import java.io.*; public class Welcome { public static void main(String args[])throws IOException { BufferedReader buf = new BufferedReader(new InputStreamReader(System.in)); System.out.println("Enter name"); String s1[]=new String[20]; int count=0; String s3 = "professor"; String s4 = "mr"; String s5 = "ms"; for(int i=0;i<20;i++) { String s = buf.readLine(); if(s.equals(" ")) { break; } s1[i]=s.toLowerCase(); count++; } for(int i=0;i<count;i++) { if(s1[i].startsWith(s3)) { System.out.println("Welcome professor"); } else if(s1[i].startsWith(s4)) { System.out.println("Welcome visitor"); } else if(s1[i].startsWith(s5)) { System.out.println("Welcome visitor"); } else { System.out.println("Welcome student"); } } } } SAMPLE OUTPUT of the above program: Enter name Professor albus MR weasly Ms Granger Harry Potter Welcome professor Welcome student Welcome visitor Welcome student Welcome visitor Welcome student Welcome student Welcome student IDEAL OUTPUT: Professor Albus Percival Wulfric Brian Dumbledore pRoFeSsOr Minerva McGonagall ProfessorSnape Professo . Sample output Welcome Professor Welcome Professor Welcome Professor Welcome Student

Entered Professor albus MR weasly Ms Granger Harry Potter Professor Albus Percival Wulfric Brian Dumbledore pRoFeSsOr Minerva McGonagall ProfessorSnape Professo Welcome professor Welcome visitor Welcome visitor Welcome student Welcome professor Welcome professor Welcome professor Welcome student it all seems to run fine... however one thing i noticed.. if u hit enter a blank line.. then the program return student.. maybe thats the problem u where having? it looks like u hit enter twice after every entry ------------ Professor albus MR weasly Ms Granger Harry Potter Welcome professor Welcome student --- Welcome visitor Welcome student --- Welcome visitor Welcome student --- Welcome student Welcome student ---- sooo if we want to fix the program a simple edit 2 the for loop is needed (i think this should work ----> CODE for(int i=0;i<20;i++) { String s = buf.readLine(); if(s.equals(" ")){ break; } else if(s.equals("")){ //a simple check.. i--; } else{ s1[i]=s.toLowerCase(); count++; } } now another little thing that could be improved in ur program: the if statments that decide what welcome message 2 print could be a shortened a little.. CODE for(int i=0;i<count;i++){ if(s1[i].startsWith(s3)){ System.out.println("Welcome professor"); } else if((s1[i].startsWith(s4))\|\|(s1[i].startsWith(s5))){ System.out.println("Welcome visitor"); } else { System.out.println("Welcome student"); } } This post has been edited by gl3thr0: 1 Jul, 2008 - 11:40 AM
