Reading integers from a file in Java -
i'm trying read integers file in java , display highest value, i'm having difficult time thinking it.
import java.util.scanner; import java.util.*; import java.io.*; public class myfile { public static void main(string[] args) throws exception { string filename; scanner in = new scanner(system.in); system.out.println("enter name of file."); filename = in.nextline(); file file = new file("myfile.txt"); scanner inputfile = new scanner(file); while(inputfile.hasnext()) { int compare = inputfile.nextint(); } } } the file called myfile.txt , has integers 23, 34, 45, , 2.
if require find highest value file, can do:
int max = integer.min_value; while(inputfile.hasnext()) { int compare = inputfile.nextint(); if (compare > max){ max = compare; } } system.out.println("highest value:"+ max); is looking for?
