I am working on below challenge
I tried my code as below
public String oneTwo(String str) {
StringBuilder sb=new StringBuilder();
int strLen=str.length();
for(int i=0;i<=strLen-3;i+2){
return sb.toString();
I am getting below result
Compile problems:

Error:      for(int i=0;i<=strLen-3;i+2){
Syntax error on token "+", invalid AssignmentOperator

see Example Code to help with compile problems

cannot i give increment as i+2 instead of i++ in for loop?

how to  improve my approach, results and design of this challenge. How do i make a graphical venn or flow chart or some other relevant diagram to design it before writing code to decide best strategy?
 Please advise
