Calling phone number cuts first zero

Question

Here is my code:

MainActivity.java

public class MainActivity extends AppCompatActivity {
    private long sTime = 0L;
    private Handler myHandler = new Handler();
    private long wait2 = 1000000000;
    private int telnum2;`

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        Button butt = (Button) findViewById(R.id.butt);
        Button buttstop = (Button) findViewById(R.id.buttstop);
        if (butt != null) {
            butt.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View view) {
                    EditText wait = (EditText) findViewById(R.id.editText2);
                    wait2 = Integer.parseInt(wait.getText().toString()) * 1000;
                    EditText telnum = (EditText) findViewById(R.id.editText);
                    telnum2 = Integer.parseInt(telnum.getText().toString());
                    sTime = SystemClock.uptimeMillis();
                    myHandler.removeCallbacks(AutoCaller);
                    myHandler.postDelayed(AutoCaller, wait2);

                }
            });
        }
        buttstop.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                myHandler.removeCallbacks(AutoCaller);
            }
        });
    }

    private Runnable AutoCaller = new Runnable() {
        @Override
        public void run() {
            final long start = sTime;
                startActivity(new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + telnum2)));
            myHandler.postDelayed(this, wait2);
        }
    };
    @Override
    protected void onPause() {
        myHandler.removeCallbacks(AutoCaller);
        super.onPause();
    }
    @Override
    protected void onResume() {
        super.onResume();
        myHandler.postDelayed(AutoCaller, wait2);
    }}

layout_main.xml

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:popupTheme="@style/AppTheme.PopupOverlay" />

</android.support.design.widget.AppBarLayout>

<include layout="@layout/content_main" />

It creates 2 EditText and 2 Buttons. I type number (0111) in first and (1) in second. I click 1st button (id:butt) and it calls number 111 (i typed 0111).

Thanks!

Thats logic: You parse the String "0111" to an Integer, but numbers never start with zero if it isnt zero itself or a float/double value. So Java removes the zero when parsing, because the zero is useless for a number, because it doesnt change the value of the number.
