Write a function that takes an input parameter as a string and return the alternate words in it with “abc”. Words are separated by dots. Note: Avoid using inbuilt functions

Input: "i.like.this.program.very.much" Output: "i.abc.this.abc.very.abc"

Would something like this work?

public String func(String s) {
    String[] arr = s.split("\\.");
    for (int i = 0; i < arr.length; i  ) {
        if (i % 2 == 1)
            arr[i]= "abc";
    }

    String rString = "";

    for (int i = 0; i < arr.length - 1; i  ) {
        rString  = arr[i];
        rString  = ".";
    }
    rString  = arr[arr.length - 1];

    return rString;
}

Not my most efficient work, but it was what I came up with on the spur of the moment.

Not sure what you exactly mean by avoiding built in methods, but this should work:

  public String whyNot(String s) {
     String[] sA = s.split("\\.");
     String newS = sA[0];
     for (int i = 1; i < sA.length; i=i 2) {
        newS  = ".abc."   sA[i];
      }
     return newS;
  }
