For loop with array

Question

I have a next loop:

arrayI = new POJO_I [response.body().length];
arrayI = response.body();
arrayOfNamesMain = new String[10];

for(int t = 0; t< arrayI.length; t++) {
    if (arrayI[t].getMain().equals("1")) {
        arrayOfNamesMain[t] = arrayI[t].getName();
    }
}

After loop ending, I have arrayOfNamesMain with a few first empty elements, so actually it starts from the 5th index because first positions of arrayI[t] are not in if statement.

What should I do for filling my arrayOfNamesMain from 0 indexes? How can I sort the array and remove empty elements?

You're asking three different things in this question. I answered the one I think it's the post about, but please make sure to make clear, concise and single questions per post. Also your title's not very good. — Ssr1369

Fill your arrayOfNamesMain using a different counter.

arrayI = new POJO_I [response.body().length];
int counter = 0;
arrayI = response.body();
arrayOfNamesMain = new String[10];

for(int t = 0; t< arrayI.length; t++) {
    if (arrayI[t].getMain().equals("1")) {
        arrayOfNamesMain[counter] = arrayI[t].getName();
        counter++;
    }
}

use a different counter variable inside if block which starts from 0 and increment it inside if block if conditions satisfy... it will solve your problem. int j = 0; arrayOfNamesMain[j] = arrayI[t].getName();
