Answer 4

In that way I got abxy but I need axby !!

Answer 5

it is not about concatenate, but about how divide this strings
String s1="ab", s2="xy";
System.out.println(
""+s1.charAt(0) +s2.charAt(0) +s1.charAt(1) +s2.charAt(1) );

you can use eg s1.substring(0,1) instead

Answer 6

StringBuilder builder = new StringBuilder(s1.length() + s2.length());
for(int i = 0; i < s1.length(); i++) {
builder.append(s1.charAt(i));
builder.append(s2.charAt(i));
}
String s3 = builder.toString();

For each valid indexes of your strings, append the characters at this index from both strings, to an accumulator.
