How to take multiple integer input in one line using BufferedReader in Java?

Please help me to solve the problem of taking multiple integer input in a single line using BufferedReader class?

In Scanner class we can take multiple input like all elements of array in one line. How to do that using BufferedReader?

According to me what you can do is take the input as a string and then divide it accordingly. If you want the input to be Integer then you can typecast it. Here is a small example for taking the input of an array in one line.

BufferedReader br = new BufferedReader(new InputStreamReader(; 
int num = Integer.parseInt(br.readLine()); //Length of Array
String s= br.readLine(); //Input the number seperated by space
int[] arr= new int[num];
String[] s1 = s.split(" ");
for(int i=0;i<num;i++)

This will work.

Try this in case you don't know the number of integers

String[] integersInString = br.readLine().split(" ");
int a[] = new int[integersInString.length];
for (int i = 0; i < integersInString.length; i++) {
    a[i] = Integer.parseInt(integersInString[i]);
