copied!<p>For more control, try the basic OOP concept of <strong>overloading methods</strong> like</p> <pre><code>public float addition(float numa, float numb) { // will return float return numa + numb; } public int addition(int numa, float numb) { // explicitly cast to int return numa + (int) numb; } public int addition(float numa, int numb) { // explicitly cast to int return (int) numa + numb; } public int addition(int numa, int numb) { // will return int return numa + numb; } </code></pre> <p>To examin your in put, try something like this...</p> <pre><code>public void examineInput(String input1, String input2) { // For both are float if (input1.indexOf(".") != -1 && input2.indexOf(".") != -1) { float numa = Float.parseFloat(input1); float numb = Float.parseFloat(input2); float ans = addition(numa, numb); Log.i(TAG, String.format("%f + %f = %f", numa, numb, ans)); } // for first to be int and second to be float else if (input1.indexOf(".") == -1 && input2.indexOf(".") != -1) { int numa = Integer.parseInt(input1); float numb = Float.parseFloat(input2); int ans = addition(numa, numb); Log.i(TAG, String.format("%d + %f = %d", numa, numb, ans)); } // for first to be float and second to be int else if (input1.indexOf(".") != -1 && input2.indexOf(".") == -1) { float numa = Float.parseFloat(input1); int numb = Integer.parseInt(input2); int ans = addition(numa, numb); Log.i(TAG, String.format("%f + %d = %d", numa, numb, ans)); } // for both to be int else if (input1.indexOf(".") == -1 && input2.indexOf(".") == -1) { int numa = Integer.parseInt(input1); int numb = Integer.parseInt(input2); int ans = addition(numa, numb); Log.i(TAG, String.format("%d + %d = %d", numa, numb, ans)); } } </code></pre> <p>And the is the input to test this code, with output</p> <pre><code>examineInput("5.2", "6.2"); // 5.200000 + 6.200000 = 11.400000 examineInput("5", "3.6"); // 5 + 3.600000 = 8 examineInput("1.6", "5"); // 1.600000 + 5 = 6 examineInput("5", "5"); // 5 + 5 = 10 </code></pre> <p><strong>Note:</strong> you need to verify that examineInput always get valid numbers, not strings of non numaric characters...</p> <p>Hope this helps to improve OOP concepts as well..:)</p>
