In Java5, a for-each loop is provided, which simplifies looping over arrays and collections. Fore-each loops allow you to iterate over an array without retaining the index in a traditional for loop or calling the hasNext method and next method in a while loop when using an iterator to iterate through the collection.
double[] values = ...;
for(double value : values) {
// TODO: 处理value
}
List<Double> valueList = ...;
for(Double value : valueList) {
// TODO: 处理value
}The above is the detailed content of Analyze examples of how to traverse collections in java. For more information, please follow other related articles on the PHP Chinese website!
