Finally is solving the issue..but else not..
public class Propagate {
public static void main(String[] args) {
String str = "";
System.out.println(reverse(str));
}
22 ->public static String reverse(String str){
String rev = "";
try{
if(str.length() == 0){
throw new StrNull();
}
for(int i=(str.length() - 1);i >= 0;i--){
rev = rev + str.charAt(i);
}
34 ->return rev;
}catch(StrNull e){
e.printStackTrace();
}catch(Exception e){
e.printStackTrace();
}
}
}
class StrNull extends Exception{
public void printStackTrace(){
System.out.println("String length is Zero..\n");
}
}
Can anyone please tell me wats the issue in this code ?in Line no 22(marked) its showing my method is not returning any string..but its returning in line 34....the issue is solving if i add a finally and return the string from there...
