大家帮忙看看--数组排序后删除重复元素的问题！
以下是我写的代码，不过这个变量number总是得不出我想要的值，请高手执教一下
public   class   SortArray   {
public   static   int[]   sortAndOptimizeArray(int[]   array)   {
Sort.sortIntegerArray(array);
int   noOfRepeats=0;
int   number=0;
for(int   i=0;i <array.length;i++)   {
boolean   ok=false;
for(int   j=i+1;j <array.length;j++)   {
if(array[i]   ==   array[j])   {
ok=true;
noOfRepeats++;
number++;
}   else   break;
}
if(ok   ==   true)   {
for(int   k=i;k <array.length;k++)   {
if((k+noOfRepeats)   <   array.length)   array[k]   =   array[k+noOfRepeats];
}
ok=false;
noOfRepeats=0;
}
}
int   len=array.length   -   number;
int[]   newArray=new   int[len];
for(int   i=0;i <newArray.length;i++)   {
newArray[i]=array[i];
}
return   newArray;
}
public   static   void   main(String[]   args)   {
    int[]   test   =   {3,   4,   3,   13,   -5,   4};
    test   =   sortAndOptimizeArray(test);  
    for(int   i=0;i   <   test.length;i++   )   {
    System.out.print(test[i]   +   ", ");
    }
    }
}
