Java Modifying array length

There is no API for modifying the length of an array in Java, where I provide two functions to modify the length of the array: Arrayaddlength () and Arrayreducelength (). See Code in detail.  [java] View Plaincopyprint?import Java.lang.reflect.Array;    /** * Description:this class is used to adjust array length. * @author E421083458 *&nbs p;*/ public class Arraytest {   /** * @param args */ public static void Main (String [] args) { int a[]= new int[]{0,1,2,3,4,5};  int b[]= new int[]{0,1,2,3,4,5};  a = (int[]) arrayaddlength ( a,2);  b = (int[]) arrayreducelength (b,2);  //out Print Array lenght  system.out.println (a.length);  for (int i=0;i<a.length;i++) { system.out.print (a[i]);  }  system.out.println ();    system.out.println (b.length);  for (int i=0;i<b.length;i++) { system.out.print (B[i]),  }  }  /** * Description: Array add length * @param oldarray * @param addlength * @return object */ public Static Object Arrayaddlength (Object Oldarray,int addlength) { class c = oldarray.getclass ();  if (!c.isarray () ) return null;  class ComponentType = C.getcomponenttype ();  int length = Array.getlength (Oldarray);  int newlength = length + addlength;  object NewArray = array.newinstance (componenttype,newlength);  system.arraycopy (oldarray,0,newarray,0,length);  return NewArray;  }  /** * description:array reduce lenght * @param oldarray * @param reducelength * @ Return object */ public Static object Arrayreducelength (Object Oldarray,int reducelength) { class c = old Array.getclass ();  if (!c.isarray ()) return null;  class ComponentType = C.getcomponenttype ();  int length = Array.getlength (Oldarray);  int newlength = length-reducelength;  object NewArray = array.newinstance (componenttype,newlength);  system.arraycopy (oldarray,0,newarray,0,newlength);  return NewArray; &nBSP;}  }
