该错误can only iterate over an array or an instance of java.lang.iterable的实例并不意味着它会阻止用户在数组或实例上使用循环。 这意味着使用的循环不能补充其条件 - 例如 for 或 foreach 循环。 使用Iterator() 解决 Can Only Iterate Over an Array or an Instance of java.lang.iterable 错误 在循环...
这条错误信息表明,在Java中,你只能对数组(Array)或实现了java.lang.Iterable接口的对象进行迭代操作。如果你尝试对一个不符合这些条件的对象进行迭代(例如,一个普通的对象或者一个基本数据类型),编译器就会抛出这个错误。 提供可能导致这个错误的常见原因 尝试对非Iterable或数组类型进行for-each循环:例如,尝试对一个普...
To iterate from the second element of an array in JavaScript, we can use one of the following functions: 1. Using for loop A for loop is a common way to iterate over an array in JavaScript. We can use it to iterate over the array from the second element to the last element, and t...

To iterate over an enum in Java using a for loop, you can use the values() method of the enum type to get an array of all the enum values, and then use a standard for loop to iterate over the array. For example, consider the following enum type: public enum Color { RED, GREEN,...

This post will discuss how to iterate over an array in JavaScript. A for-loop repeats until a specified condition evaluates to false. The JavaScript syntax remains similar to C and Java-style for-loop.
Hi Lee – try saving each iteration value to array and if required in multidimensional array. Are you looking for complete code? Or conceptually? Reply kukugtsays Aug 17, 2018 at 2:15 am Best Time of the 5 ways: For Loop: 0.015s ...
for循环对象必须是数组或list对象 orderIterator.next()只是单一的对象 你既然用了while循环怎么还用for循环呢
