I can not get my code to comply it gets mad that I have run declare more than once. Please help me figure out how to get this to work package projectOne; import java.io.File; import java.io.FileNotFoundException; import java.util.ArrayList; import java.util.Scanner; import java.util.*; import java.io.*; public class Main { public static void main(String[] pArgs){ Main mainObject = new Main(); mainObject.run(); } private void run() { public FileReader readFile() throws FileNotFoundException { FileReader file = new FileReader(\"p01-in.txt\"); return file; } public ArrayList<Integer> getData(FileReader file) throws FileNotFoundException { Scanner data_read = new Scanner(new BufferedReader(file)); ArrayList<Integer> data = new ArrayList<Integer>(); while (data_read.hasNext()) { int item = data_read.nextInt(); data.add(item); } return data; } public ArrayList<Integer> calcRuns(ArrayList<Integer> data) { ArrayList<Integer> runs = new ArrayList<Integer>(); Iterator<Integer> i_data = data.iterator(); int run = 0; int temp = i_data.next(); while (i_data.hasNext()) { int t1 = i_data.next(); if (temp < t1) run++; else { runs.add(run); run = 0; } temp = t1; } i_data = data.iterator(); temp = i_data.next(); run = 0; while (i_data.hasNext()) { int t1 = i_data.next(); if (temp > t1) run++; else { runs.add(run); run = 0; } temp = t1; } return runs; } public void writeOutput(ArrayList<Integer> runs) throws IOException { PrintWriter out = new PrintWriter(new File(\"p01-runs.txt\")); ArrayList<Integer> run_count = new ArrayList<Integer>(); int i = 0; int r_count = Collections.frequency(run_count, i); while (i < 100) { run_count.add(r_count); i++; r_count = Collections.frequency(runs, i); } Iterator<Integer> i_runs = run_count.iterator(); i = 0; while (i_runs.hasNext()) { int run = i_runs.next(); String line = \"run_\" + i + \" ,\" + run; i++; out.println(line); } } public void run() throws Exception { FileReader fin = this.readFile(); ArrayList<Integer> data = this.getData(fin); ArrayList<Integer> runs = this.calcRuns(data); this.writeOutput(runs); } } Solution In your program you have to change the syntax errors at method declaration.so your not getting output. .

1. I can not get my code to comply it gets mad that I have run declare more than once. Please help
me figure out how to get this to work
package projectOne;
import java.io.File;
import java.io.FileNotFoundException;
import java.util.ArrayList;
import java.util.Scanner;
import java.util.*;
import java.io.*;
public class Main
{ public static void main(String[] pArgs){
Main mainObject = new Main();
mainObject.run();
} private void run() {
public FileReader readFile() throws FileNotFoundException {
FileReader file = new FileReader("p01-in.txt");
return file;
}
public ArrayList<Integer> getData(FileReader file) throws FileNotFoundException {
Scanner data_read = new Scanner(new BufferedReader(file));
ArrayList<Integer> data = new ArrayList<Integer>();
while (data_read.hasNext()) {
int item = data_read.nextInt();
data.add(item);
}
return data;
}
public ArrayList<Integer> calcRuns(ArrayList<Integer> data) {
ArrayList<Integer> runs = new ArrayList<Integer>();
Iterator<Integer> i_data = data.iterator();
int run = 0;
int temp = i_data.next();
while (i_data.hasNext()) {
int t1 = i_data.next();
if (temp < t1)
run++;
else {
runs.add(run);
run = 0;
}
temp = t1;
}
i_data = data.iterator();

2. temp = i_data.next();
run = 0;
while (i_data.hasNext()) {
int t1 = i_data.next();
if (temp > t1)
run++;
else {
runs.add(run);
run = 0;
}
temp = t1;
}
return runs;
}
public void writeOutput(ArrayList<Integer> runs) throws IOException {
PrintWriter out = new PrintWriter(new File("p01-runs.txt"));
ArrayList<Integer> run_count = new ArrayList<Integer>();
int i = 0;
int r_count = Collections.frequency(run_count, i);
while (i < 100) {
run_count.add(r_count);
i++;
r_count = Collections.frequency(runs, i);
}
Iterator<Integer> i_runs = run_count.iterator();
i = 0;
while (i_runs.hasNext()) {
int run = i_runs.next();
String line = "run_" + i + " ," + run;
i++;
out.println(line);
}
}
public void run() throws Exception {
FileReader fin = this.readFile();
ArrayList<Integer> data = this.getData(fin);
ArrayList<Integer> runs = this.calcRuns(data);
this.writeOutput(runs);
}
}

3. Solution
In your program you have to change the syntax errors at method declaration.so your not getting
output.
