I've tried out, and it worked. Thanks.

This is the class with static method sortArray, which would sort 
your array in the sense you want it (see output): 
 

<pre><code class="code-10 nolinks" id="code-20-36912163-1">import java.util.Arrays;

public class MyString implements Comparable&lt;MyString&gt; {
 String s;
 public MyString(String s){
 this.s = s;
 }

 public String getString(){ return s;}

 public int compareTo(MyString ms1){
 float f = -1.0f;
 float f1 = -1.0f;
 String s1 = ms1.getString();
 boolean first = true;
 boolean second = true;

 try{
 f = Float.parseFloat(s);
 } catch(Exception ex){
 first = false;
 }

 try{
 f1 = Float.parseFloat(s1);
 } catch(Exception ex){
 second = false;
 }

 if(first &amp;&amp; !second)return -1;
 if(!first &amp;&amp; second)return 1;
 if(first &amp;&amp; second){
 if(f&lt;f1)return -1;
 else return 1;
 }
 if((!first) &amp;&amp; (!second)){
 return s.compareTo(s1);
 }

 return 1;
 }

 public static String [] sortArray(String [] arr){
 MyString[] myss = new MyString[arr.length];
 for(int j=0; j&lt;arr.length; j++){
 myss[j]= new MyString(arr[j]);
 }

 Arrays.sort(myss);
 String [] ss = new String[myss.length];

 for(int j=0; j&lt;arr.length; j++){
 ss[j]= myss[j].getString();
 }

 return ss;

 }

 public static void main(String[] args) {
 String [] ss = { &quot;0&quot;, &quot;c&quot;, &quot;b&quot;, &quot;1.2&quot;, &quot;0.2&quot;, &quot;a&quot;};
 ss = MyString.sortArray(ss);
 for(String s: ss){
 System.out.println(s);
 }

 }

}

Output: 

<pre><code class="code-1 nolinks" id="code-20-36912163-2">0
0.2
1.2
a
b
c
</code></pre>

Thank you very much, for_yan.

<div class="content wysiwyg-content">
I have a array: 0, a, b, 1.2, 0.2, c 
I'd like to sort them by number first, then by alphabetic 
result should be: 
0, 0.2, 1.2, a, b, c 
 
How can I do this?

sort an array with float and string

Java is a platform-independent, object-oriented programming language and run-time environment, designed to have as few implementation dependencies as possible such that developers can write one set of code across all platforms using libraries. Most devices will not run Java natively, and require a run-time component to be installed in order to execute a Java program.
