You can often improve the performance of migrated code by replacing the Collection object with one of the types defined in the System.Collection namespace, for example the ArrayList or HashTable objects. If the collection holds items of same type, you can also use the strong-typed List(Of T...

换句话说,我们有一个包含元素的数组,并将其转换为List,然后将该列表转换为ArrayList。查看下面的示例以了解发生了什么。 importjava.util.*;publicclassHello{publicstaticvoidmain(String[]args){String arr[]={"1","2","3"};List<String>MyList=(List<String>)Arrays.asList(arr);// now we are convert...
