Here is my code :
public static void Max(List<List<String>> data) {
data.forEach(d -> String max = Collections.max(Arrays.asList(d.getMax(5))));
}
The result I get:
70
75
76
How can I get only the maximum number?

You can use Comparator.comparing to compare the 2nd index and parse as Integer when compare then get the second index element from the list.
String res = Collections.max(data,
Comparator.comparing(e -> Integer.parseInt(e.get(2)))).get(2);

A more simple way:
int max = Integer.MIN_VALUE;
for (int i = 0; i < data.size(); i++) {
for (int j = 0; j < data.get(i).size(); j++) {
max = Integer.max(Integer.parseInt(data.get(i).get(j)), max);
}
}
System.out.println(max);
This way we comb through every member of each list and by invoking max() we get the max number, which is then displayed in the console.
