I have a dataset that lists different activities done in each day in a string array, similar concept asked here. Each activity is delimited and can easily be separated into columns, as I've had no problem doing in Excel.
activites
Work | family | date | gaming | relax | good sleep | shopping
Work | family | date | Nature | Crusin | reading | gaming | relax | good sleep | cooking | laundry
family | date | movies & tv | gaming | sport | relax | medium sleep | cooking
Work | family | date | Photography | gaming | relax | good sleep | medium sleep | cooking
Work | family | date | Nature | reading | gaming | relax | good sleep | cleaning
What I am trying to do is make each activity into a boolean variable which has its own column as such, so it indicates 0 for not having done the activity on that day and 1 for having done the activity. It would look something like this:
Work Family Date Gaming Relax
1 1 0 1 0
1 1 1 0 0
0 0 1 0 1
So, what I ended up doing was using my knowledge of Java to reformat data. I first separated the activities into their own variables, each containing a numerical (binary) value to indicate whether or not that activity had been done that day. I had to treat sleep quality separately, so that part looks a little wonky. Here's the code, which produced the correct output:
public static void main(String[] args) throws FileNotFoundException {
Scanner scan = new Scanner(new FileReader("activities.txt"));
String[] actList = { "Work", "school", "family", "friends", "date", "nature", "crusin", "photography",
"making music/piano", "movies & tv", "reading", "gaming", "sport", "relax", "sleep", "shopping", "cleaning",
"cooking", "laundry" };
int row = 0;
while (scan.hasNextLine()) {
row++;
int col = 0;
int activityNo = 0;
int[] actValue = new int[actList.length];
String pipeDelim = scan.nextLine();
String[] actName = pipeDelim.split(" \\| ");
int sleepTagsUsed = 0;
while (activityNo < actName.length) {
col = 0;
for (String a : actName) {
if (a.contains("sleep")) {
col = 14;
if (a.equalsIgnoreCase("bad sleep") || a.equalsIgnoreCase("bad sleep\t")) {
if (col < actList.length) {
actValue[col] = 0;
if (sleepTagsUsed == 0) {
col++;
}
sleepTagsUsed++;
} else {
break;
}
if (!(activityNo > actName.length)) {
activityNo++;
}
} else if (a.equalsIgnoreCase("medium sleep") || a.equalsIgnoreCase("medium sleep\t")) {
if (col < actList.length) {
actValue[col] = 1;
if (sleepTagsUsed == 0) {
col++;
}
sleepTagsUsed++;
} else {
break;
}
if (!(activityNo > actName.length)) {
activityNo++;
}
} else if (a.equalsIgnoreCase("good sleep") || a.equalsIgnoreCase("good sleep\t")) {
if (col < actList.length) {
actValue[col] = 2;
if (sleepTagsUsed == 0) {
col++;
}
sleepTagsUsed++;
} else {
break;
}
if (!(activityNo > actName.length)) {
activityNo++;
}
} else if (a.equalsIgnoreCase("sleep early") || a.equalsIgnoreCase("sleep early\t")) {
if (col < actList.length) {
actValue[col] = 3;
if (sleepTagsUsed == 0) {
col++;
}
sleepTagsUsed++;
} else {
break;
}
if (!(activityNo > actName.length)) {
activityNo++;
}
} else {
if (col < actList.length) {
actValue[col] = -1;
} else {
break;
}
System.out.println("No sleep logged error");
}
} else {
int j = 0;
for (String i : actList) {
if (a.equalsIgnoreCase(i) || a.equalsIgnoreCase(i + "\t")) {
actValue[col] = 1;
if (activityNo > actName.length) {
break;
} else {
activityNo++;
break;
}
} else {
if (col < actList.length) {
j++;
if (j > col) {
actValue[col] = 0;
col++;
}
} else {
break;
}
}
}
col++;
}
}
}
for (int p : actValue) {
System.out.print(p + "\t");
}
System.out.println();
}
scan.close();
}
