我想要下面的代码降序排序类型:
这是升序排序:
public static <T extends Vm> void sortByCpuUtilization(List<T> vmList) {
Collections.sort(vmList, new Comparator<T>() {
@Override
public int compare(T a, T b) throws ClassCastException {
Double aUtilization = a.getTotalUtilizationOfCpuMips(CloudSim.clock());
Double bUtilization = b.getTotalUtilizationOfCpuMips(CloudSim.clock());
return bUtilization.compareTo(aUtilization);
}
});
}
最佳答案
将a与b进行比较:
public static <T extends Vm> void sortByCpuUtilization(List<T> vmList) {
Collections.sort(vmList, new Comparator<T>() {
@Override
public int compare(T a, T b) throws ClassCastException {
Double aUtilization = a.getTotalUtilizationOfCpuMips(CloudSim.clock());
Double bUtilization = b.getTotalUtilizationOfCpuMips(CloudSim.clock());
return aUtilization.compareTo(bUtilization);
}
});
}
