Cannot make this code work properly
<p>How do I make it show answers randomly on one of 4 lines, without having any duplicates?</p>

<p>My current code:</p>

<pre><code>TextView question;
private int qType = -1;
private int asked = 0;
private void QBegin() {
    /*
     * Gets a random question
    */
    question = (TextView) findViewById(R.id.question);
    String[] types = { "Q1", "Q2", "Q3", "Q4", "Q5"};
    Random random = new Random();
    int qType = random.nextInt(types.length);
    question.setText(types[qType]);
    asked++;
   // StringList.add(types[qType]);
    getAnswers(qType);
 /*   if(StringList.contains(types[qType]) &amp;&amp; asked &gt;= types.length+1){
        asked = 0;
        answerCounter.setText("THE END");
    } else if (StringList.contains(types[qType]) &amp;&amp; asked &lt; types.length+1){
        QBegin();
    } */
}
     public static int random(int range) {
    return (int)(java.lang.Math.random() * (range+1));
}

public void shuffle(String input){
    /*
     * Unused shuffle method
     */
    List&lt;Character&gt; characters = new ArrayList&lt;Character&gt;();
    for(char c:input.toCharArray()){
        characters.add(c);
    }
    StringBuilder output = new StringBuilder(input.length());
    while(characters.size()!=0){
        int randPicker = (int)(Math.random()*characters.size());
        output.append(characters.remove(randPicker));
    }
    System.out.println(output.toString());
}
private void getAnswers(int Type) {
    /* 
     * Getting answers here
     */
    int randomValue = random(4);
    try { 
    String answers_list[][] = {
            {"Answer 1-1", "Answer 2-1", "Answer 3-1", "Answer 4-1"}, 
            {"Answer 1-2", "Answer 2-2", "Answer 3-2", "Answer 4-2"},
            {"Answer 1-3", "Answer 2-3", "Answer 3-3", "Answer 4-3"},
            {"Answer 1-4", "Answer 2-4", "Answer 3-4", "Answer 4-4"},
            {"Answer 1-5", "Answer 2-5", "Answer 3-5", "Answer 4-5"}} ;
    answer1.setText(answers_list[Type][randomValue+1 &gt; 3 ? (randomValue+0)-4 : randomValue+0]); 
    answer2.setText(answers_list[Type][randomValue+2 &gt; 3 ? (randomValue+1)-3 : randomValue+1]); 
    answer3.setText(answers_list[Type][randomValue+3 &gt; 3 ? (randomValue+2)-2 : randomValue+2]); 
    answer4.setText(answers_list[Type][randomValue+0 &gt; 3 ? (randomValue+3)-4 : randomValue+3]);


    /*for (int rows = 0; rows &lt; answer&amp;*list.length; rows++){
    for (int cols = 0; cols &lt; answers_list[rows].length; cols++){   
      }
        }*/
    } catch(Exception ex){
    answer1.setText("Error "+ex);
    }

<p>Code that's responsible for picking &amp; adding questions on one of 4 lines (randomly)</p>

<pre><code>    answer1.setText(answers_list[Type][randomValue+1 &gt; 3 ? (randomValue+0)-4 : randomValue+0]); 
    answer2.setText(answers_list[Type][randomValue+2 &gt; 3 ? (randomValue+1)-3 : randomValue+1]); 
    answer3.setText(answers_list[Type][randomValue+3 &gt; 3 ? (randomValue+2)-2 : randomValue+2]); 
    answer4.setText(answers_list[Type][randomValue+0 &gt; 3 ? (randomValue+3)-4 : randomValue+3]);
</code></pre>

<p>At the moment, I'm having duplicates with answer1 and answer4. Please Help.</p>
