How set input file in Jquery?

How to find mode from array of numbers/ prompt user for file?

• New to Java. Ran into a wall with these errors. Below are instructions, errors my code. Intstructions: •Prompt the user for the name of an input file. •The input file will contain an unknown number of integers (one per line) ranging from -9 to +9 (* This represents a change from the previous lab, but not one that should affect your previous code in any way... if it was written "correctly".) •Display the "statistical mode" (most frequently occurring value) of the set of input values. •Don't worry about the case of a tie. For example if 4 and 7 both occur 40 times, either value is acceptable. Errors: run: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - non-static method findMode(int[]) cannot be referenced from a static context at lab1.LAB1.Mode(LAB1.java:27) at lab1.LAB1.main(LAB1.java:21) Java Result: 1 BUILD SUCCESSFUL (total time: 3 seconds) My Code: package lab1; import java.io.File; import java.io.FileNotFoundException; import java.util.Arrays; import java.util.Scanner; public class LAB1 { public static int[] arr=new int[] {1,2,3,3,3,3,4,5,6,7}; public static void main(String[] args) throws FileNotFoundException { // Frequencies of all values in file (-9...9) int[] frequencies = new int[19]; String fileName = "H:/lab1_input.txt"; File in = new File(fileName); Mode(); } private static void Mode() { int mode=findMode(arr); System.out.println(mode); } int findMode(int[] arr){ int mode=-1; int modefreq=-1; for (int i=0;i<arr.length;i++){ int current=arr[i]; int freq=howMany(arr,current); if (freq>modefreq){ mode=current; modefreq=freq; } } return(mode); } public static int howMany(int[] arr,int c){ int howm=0; for (int i=0;i<arr.length;i++){ if (arr[i]==c) howm++; } return (howm); } }

• Answer:

  That error pretty much tells you what's wrong: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - non-static method findMode(int[]) cannot be referenced from a static context You're trying to use a non-static method like it was a static method. findModel(int[] arr) is the only non-static method in your program. To fix: make it static!
