title: how to get the minimum,maximum value of an array?
body: <p>Here's my code. I need to get the minimum,maximum value of my array to be able for me get the range, whenever I input numbers the minimum value is 0. Please help me. Thank you:)</p>
  
  <pre><code>final AutoCompleteTextView inputValues = (AutoCompleteTextView) findViewById(R.id.txt_input);
  final TextView txtMinimum = (TextView) findViewById(R.id.txtMinimum);
  final TextView txtMaximum = (TextView) findViewById(R.id.txtMaximum);
  final TextView txtRange = (TextView) findViewById(R.id.txtRange);
  
  Button btncalculate = (Button)findViewById(R.id.btncalculate);
  btncalculate.setOnClickListener(new OnClickListener() {
  
      @Override
      public void onClick(View arg0) {
          String []values = ( inputValues.getText().toString().split(","));
          int[] convertedValues = new int[values.length];
  
          // calculate for the minimum and maximum number
          int min = 0;
          int max=0;
  
          min = max = convertedValues[0];
          for (int i = 0; i &lt; convertedValues.length; ++i) {
              convertedValues[i] =Integer.parseInt(values[i]);
              min = Math.min(min, convertedValues[i]);
              max = Math.max(max, convertedValues[i]);
          }
          txtMinimum.setText(Integer.toString(min));
          txtMaximum.setText(Integer.toString(max));
  
          // calculate for the range
          int range=max - min;
          txtRange.setText(Integer.toString(range));
  
      }});
