Java StringBuilder Example

Write a method ..

public static int[] append(String[] a,String[] b)

that appends one array(of Strings) to another.
For example, if
a ={qqq www eee}
b ={ aaa, sss, ddd}

result ={qqq, www, eee, aaa, sss, ddd}

SOLUTION: 

  
public class StringBuilderExample {
 
 public static void main(String args[])
 {
  String a[]={"qqq", "www", "eee"};
  String b[]={"aaa", "sss", "ddd"};
  
  for ( String j : (append(a,b)) ) {
   System.out.print(j+" ");
  }
 }
 
 public static String [] append(String a[], String b[]) {
  int i=a.length+b.length;
  String result[] = new String[i];
  System.arraycopy(a, 0, result, 0,a.length);
  System.arraycopy(b, 0, result, a.length, b.length);
 
  return result;
 }
}
