Im trying to run a for loop that prints each users score in an array list. I don't know how to output who has the greatest/highest score however. Can someone please help me?
for (int i = 0; i < playersList.size(); i++) {
System.out.println("Player " + (i + 1) + ", "
+ playersList.get(i).getName() + " Score: " + playersList.get(i).getTotalScore());
playersList.get(i).getFrameScores();
System.out.println("**************");
}
First, find the max score using one iteration over your elements in list. Then, use another iteration to seek whose players have the max score and print them.
Here's a pseudocode for the above algorithm:
int maxScore <- Integer.MIN_VALUE
for each player in playerList
if maxScore < player->score then
maxScore <- player->score
end if
end for
//now you have the max score
for each player in playerList
if player-> score == maxScore then
show player info
end if
end for
Comparator if needed for the score comparison.Try this:
double maxScore = playersList.get(0).getTotalScore();
ArrayList<String> maxNames = new ArrayList();
maxNames.add(playersList.get(0).getName());
for (int i = 1; i < playersList.size(); i++) {
if(playersList.get(i).getTotalScore() > maxScore) {
maxScore = playersList.get(i).getTotalScore();
maxNames.clear();
}
if(playersList.get(i).getTotalScore() >= maxScore ) {
maxNames.add(playersList.get(i).getName());
}
}
StringBuilder names = "";
for(int i=0; i<maxNames.size(); i++) {
names.append(maxNames.get(i));
if(i != maxNames.size() - 1) {
names.append(", ");
}
}
System.out.println("The player" + (maxNames.size() > 1 ? "s" : "") + " with the highest score " + (maxNames.size() > 1 ? "are" : "is") + " " + names + ", with a score of " + maxScore + ".");
Assign the first value as max and compare every coming values. If coming value is large set it as max and compare it with remaining.
For ex
var max =0;
for(i=o;i<5;i++) {
if(i==0){ var max = a[i]; }
if(max < a[i]) {
max= a[i];
}
}
alert(max);
