Sj Yard

An app is being developed.
What is the best approach to proceed before starting?

Method 1:
- flow chart
- have all Layouts designed
- code all .java files
- link them all in manifest


Method 2:
- flow chart
- have all layouts designed
- code one .java and link it in manifest and then move on to coding the next .java


Method 3:
- flow chart
- first layout designed -> .java coded -> link in manifest
- second layout designed -> .java coded -> link in manifest
- repeat

Please advice which is the best approach.

got it!

public String missingChar(String str, int n) { char[] c; c=str.toCharArray(); String s=""; for(int i=0;i<n;i++){ s+=c[i]; } for(int i=(n+1);i<str.length();i++){ s+=c[i]; } return s; }
Sorry for troubles.

Given a non-empty string and an int n, return a new string where the char at index n has been removed. The value of n will be a valid index of a char in the original string

solution:

public String missingChar(String str, int n) { String s=""; for(int i=0;i<n;i++){ s+=str[i]; } for(i=(n+1);i<str.length();i++){ s+=str[i]; } }[Added code tags - see UseCodeTags for more details]

I need help converting String str into an Array so I can eliminate a letter from the array at the desired index.
Please.
