创建固定大小的list

List fixedSizeList = FixedSizeList.decorate(Arrays.asList(new Integer[4]));
fixedSizeList.set(0,1);
fixedSizeList.set(1,2);
fixedSizeList.set(2,3);
fixedSizeList.set(3,4);
for(int i=0;ierr.println("src:" + fixedSizeList.get(i));//1,2,3,4
}
System.err.println("**********************************");
fixedSizeList.set(0,4);
fixedSizeList.set(1,3);
fixedSizeList.set(2,2);
fixedSizeList.set(3,1);
for(int i=0;ierr.println("src:" + fixedSizeList.get(i)); // 4,3,2,1
}
System.err.println(">>>>>>>>>>length:" + fixedSizeList.size()); //4
如果继续调用set()，则会抛出Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException:4.
