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
To iterate over elements of String Array, use any of the Java Loops like while, for or advanced for loop. The index of string array starts from 0 to array length – 1. We can use this information and write a loop to iterate over string array elements. In this tutorial, we will learn...

The code demonstrates how to iterate over a 2D list (list of lists) in Java by using nested for-each loops. It prints the elements of each inner list in the desired format. Algorithm Step 1 Import necessary libraries for the code. Step 2 Create the "iterateUsingForEach" function, which...

We will copy all the array elements from carBrands to another array using the forEach method. Let’s declare an empty array called copyOfCarBrands.let copyOfCarBrands: string[] = []; Let’s use the forEach method to iterate over each element in the carBrands array and push it to ...
Then print the elements of the array on the screen using fmt.Println() function. Step 3 ? Now, using the for loop iterate over each element of the array and print them on the screen using fmt.Println() function. Example Golang program to iterate over the array using for loop. Open ...
