Examlex · Accepted Answer

The Answer is There are many ways to solve any programming problem. Here are three common correct solutions we saw:
// longer solution; pull first post out of fencepost
public static void longestName(Scanner console, int names) {
System.out.print("name #1? ");
String longest = console.next();
int count = 1;
for (int i = 2; i <= names; i++) {
System.out.print("name #" + i + "? ");
String name = console.next();
if (name.length() == longest.length()) {
count++;
}
if (name.length() > longest.length()) {
longest = name;
count = 1;
}
}
String fixedName = longest.substring(0, 1).toUpperCase();
fixedName = fixedName + longest.substring(1).toLowerCase();
System.out.println(fixedName + "'s name is longest");
if (count > 1) {
System.out.println("(There was a tie!)");
}
}
// shorter solution; boolean flag
public static void longestName(Scanner console, int names) {
String longest = "";
boolean tie = false;
for (int i = 1; i <= names; i++) {
System.out.print("name #" + i + "? ");
String name = console.next();
if (name.length() > longest.length()) {
longest = name;
tie = false;
} else if (name.length() == longest.length()) {
tie = true;
}
}
longest = longest.substring(0, 1).toUpperCase() + longest.substring(1).toLowerCase();
System.out.println(longest + "'s name is longest");
if (tie) {
System.out.println("(There was a tie!)");
}
}
// store longest two strings and compare
public static void longestName(Scanner console, int n) {
String longest = "";
String longest2 = "";
for (int i = 1; i <= n; i++) {
System.out.print("name #" + i + "? ");
String name = console.next();
if (name.length() > longest.length()) {
longest = name;
longest2 = name;
} else if (name.length() == longest.length()) {
longest2 = name;
}
}
String capitalized = longest.toUpperCase().charAt(0) + longest.toLowerCase().substring(1);
System.out.println(capitalized + "'s name is longest");
if (!longest.equalsIgnoreCase(longest2)) {
System.out.println("(There was a tie!)");
}
}
