我试图总结一个数组列表中的每个数组列表。我假设您使用 get 方法。但我不确定如何做到这一点。这就是我到目前为止所拥有的。如箭头所示,我是否正在尝试在新的arraylist 上开始之前添加arraylist。有任何想法吗?????
public void sparseCountTimer(ArrayList arraylist)
{
double totalRowsCount = 0.0;
long totalTime = 0;
for (int x = 0; x < iteration; x++)
{
long startTime2 = 0,
estimatedTime2 = 0;
double rowTotal = 0.0,
lastRowTotal = 0.0;
for( int i = 0; i < matrixDimension; ++i)
{
if (lastRowTotal < rowTotal)
{
lastRowTotal = rowTotal;
startTime2 = System.nanoTime();
}
rowTotal = 0.0;
for (int j = 0; j < matrixDimension; ++j)
{
>>>>>>>>> rowTotal += arraylist.get(j).get(i); <<<<<<<<<<<<<<
}
estimatedTime2 = System.nanoTime() - startTime2;
}
totalRowsCount += lastRowTotal;
totalTime += estimatedTime2;
}
}
