[英]How to synchronize loop in java so I could increment loop value manually (when some execution is complete)
I have a simple scenario.我有一个简单的场景。
I want to make calls to a async method (probably an api call) inside loop.我想在循环内调用异步方法(可能是 api 调用)。 I want to call the same api multiple times but don't execute the next api call until previous one is complete.
我想多次调用相同的 api 但在前一个调用完成之前不要执行下一个 api 调用。
for(int i = 0; i < 10; i++){
apicall{
apiresult
}
}
The above method will run the loop 10 times normally without waiting for the api call method to be finished.上述方法将正常运行循环 10 次,无需等待 api 调用方法完成。 what I want to do is call the next api after previous one is complete.
我想做的是在前一个完成后调用下一个 api。
For example:-例如:-
for(int i = 0; i < 10; i++){
apicall{
apiresult
// RUN NEXT LOOP AFTER THIS IS COMPLETE
}
}
I tried using while
loop but it was too slow and not reliable.我尝试使用
while
循环,但它太慢且不可靠。
You could use recursion.你可以使用递归。 Something along these lines:
这些方面的东西:
void makeAPICalls(int numberOfCalls) {
numberOfCalls--;
if (numberOfCalls > 0) {
apiCall {
apiResult
// when result arrives call this again
makeAPICalls(numberOfCalls)
}
}
}
You would then call the function like this: makeAPICalls(10)
然后,您可以像这样调用 function:
makeAPICalls(10)
