What is the best way to split an array in a Java method into smaller arrays? I want to be able to put arrays of any size into takereceipts (string [])
//Can handle any size array
public void takeReceipts(String[] receipts){
//split array into smaller arrays,and then call handleReceipts(String[]) for every smaller array
}
//This method can only handle arrays with the size of 5 or less
private void handleReceipts(String[] receipts){
myNetworkRequest(receipts);
}
Edit:
Therefore, copying an array to another array seems inefficient Will this happen?
public void takeReceipts(String[] receipts){
int limit = 5;
int numOfSmallerArrays = (receipts.length/limit)+(receipts.length%limit);
int from = 0;
int to = 4;
for (int i = 0; i < numOfSmallerArrays; i++){
List<String> subList = Arrays.asList(receipts).subList(from,to);
from =+ limit;
to =+ limit;
}
}
Solution
You can use arrays copyOfRange():
int from = 0; int to = 4; String[] subArray = Arrays.copyOfRange(receipts,from,to)
