The elements of an ArrayList<T> in Java are homogeneous.Group of answer choicesTrueFalse

Analyzing the Question

1. An ArrayList<T> in Java is a part of the Java Collections Framework and is used to store a list of objects.
2. The type parameter <T> denotes the type of elements that the ArrayList can hold.
3. The question is asking whether the elements of an ArrayList<T> are homogeneous, meaning they are of the same type.

Relevant Concepts

1. Homogeneous Collections: In the context of generics in Java, when we declare an ArrayList<T>, the elements in this list are expected to be of the type defined by T.
2. Generics in Java: Java uses generics to allow type-safe operations. If T is specified as String, for instance, then the ArrayList<T> will only hold String objects.

Analysis and Detail

1. If you create an ArrayList<String>, then every element in that list has to be a String. This characteristic enforces homogeneity among the elements in the list.
2. If you attempt to add an element of a different type (e.g., an Integer), the compiler will throw an error, thereby ensuring that all elements are of the same type as defined by T.

Verify and Summarize

The definition of ArrayList<T> indicates that the elements must be of the same type specified by the type parameter. Therefore, we can affirm that the elements of an ArrayList<T> are indeed homogeneous.

Final Answer

True: The elements of an ArrayList<T> in Java are homogeneous, as they are all of the same type defined by the type parameter T.
