The error occurs because the `NoSuchElementException` is thrown when the `Scanner.nextLine()` method is called, but there is no input available to read.
Why does the error occur in the given code?The error occurs in the given code because the `Scanner.nextLine()` method is being called to read input from the user, but there is no input available to be read. This can happen if there is no more input left in the input stream or if the user does not provide any input when prompted.
In this specific code snippet, the error occurs at line 72 (`cno=keyboard1.nextLine();`) and line 75 (`sec=keyboardi.nextLine();`). These lines expect the user to input values for `cno` and `sec` respectively using the `Scanner.nextLine()` method. However, if there is no input provided by the user, the `NoSuchElementException` is thrown because the `Scanner` cannot find a line to read.
To resolve this error, ensure that the user provides the required input when prompted. You can also check if there is input available using the `Scanner.hasNextLine()` method before calling `nextLine()` to avoid the exception.

When stacking interlocking rows should be used to minimize:________
When stacking, interlocking rows should be used to minimize movement and ensure stability.
What is stacking?
Stacking refers to the process of stacking products or materials on top of one another. Stacking is an excellent approach to optimize space and provide easy access to inventory items. Stacking, on the other hand, must be performed appropriately to ensure that it is safe and stable. There are many stacking methods, and each of them has its own set of benefits and drawbacks.
What are interlocking rows?
Interlocking rows are a form of stacking method that is commonly used to maximize stability and reduce movement. When using this technique, items are placed in rows with alternating placement. The interlocking rows help distribute weight evenly throughout the stack, minimizing the risk of collapse due to uneven weight distribution. This method is especially useful when stacking irregularly shaped objects or items that have different sizes or weights.
The benefit of using interlocking rows when stacking is that it ensures stability and minimizes movement. This reduces the risk of damage or injury caused by collapsing stacks. When stacking items, it is essential to use a method that is appropriate for the type of item being stacked and the storage conditions.
