在Java中遍历多个变量

int[] numbers = {1, 2, 3, 4, 5};
for (int i = 0; i < numbers.length; i++) {
    System.out.println(numbers[i]);
}

int[] numbers = {1, 2, 3, 4, 5};
for (int number : numbers) {
    System.out.println(number);
}

List<String> names = new ArrayList<>();
names.add("Alice");
names.add("Bob");
names.add("Charlie");
Iterator<String> iterator = names.iterator();
while (iterator.hasNext()) {
    String name = iterator.next();
    System.out.println(name);
}

List<String> names = new ArrayList<>();
names.add("Alice");
names.add("Bob");
names.add("Charlie");
for (String name : names) {
    System.out.println(name);
}

Map<String, Integer> scores = new HashMap<>();
scores.put("Alice", 90);
scores.put("Bob", 80);
scores.put("Charlie", 70);
for (Map.Entry<String, Integer> entry : scores.entrySet()) {
    String name = entry.getKey();
    int score = entry.getValue();
    System.out.println(name + ": " + score);
}
