How to Iterate Through a Java List Using StringTemplate

How can I iterate through a Java List while utilizing StringTemplate for text generation?

List<String> items = Arrays.asList("Apple", "Banana", "Cherry");
StringTemplate template = new StringTemplate("Item: $item$\n");

for (String item : items) {
    template.setAttribute("item", item);
    System.out.println(template.toString());
}

Iterating through a Java List with StringTemplate allows for dynamic text generation based on elements in the list. Below, we explore how to accomplish this effectively and provide relevant examples.

List<String> fruits = Arrays.asList("Mango", "Pineapple", "Grapes");
StringTemplate fruitTemplate = new StringTemplate("Fruit name: $fruit$\n");

for (String fruit : fruits) {
    fruitTemplate.setAttribute("fruit", fruit);
    System.out.print(fruitTemplate.toString());
    fruitTemplate.reset(); // Reset the template for the next iteration
}

Causes

• Not using the correct StringTemplate version that supports the required features.
• Failing to set attributes in the StringTemplate properly before outputting.

Solutions

• Ensure you have the latest version of StringTemplate that fits your requirements.
• Use the setAttribute method correctly to bind list items to the template.

Mistake: Not resetting the StringTemplate after each iteration can lead to incorrect output.

Solution: Use the reset() method after each use of the template to clear previously set attributes.

Mistake: Incorrectly setting attributes can lead to a runtime error, resulting from a non-existing variable in the template.

Solution: Ensure the attribute name matched in the setAttribute method corresponds exactly to the variable in the template.
