The purpose of the notation <> (diamond operator) in the given statement is to specify the type of objects that the ArrayList will hold.

In Java, the diamond operator <> is used to implement type inference, introduced in Java 7. It allows the programmer to omit the type declaration on the right-hand side of an assignment when the type information can be inferred from the left-hand side. In the context of the statement creating an ArrayList object, the diamond operator is used to provide type information for the ArrayList. For example, consider the statement: ArrayList<String> myList = new ArrayList<>();. Here, the diamond operator <> is used after the ArrayList class to specify that the ArrayList object will hold objects of type String. The type information is inferred from the variable declaration on the left-hand side (ArrayList<String> myList), allowing the programmer to omit the type declaration when creating the object.

The diamond operator simplifies the code by reducing redundancy and improving code readability. It ensures that the ArrayList object created will be of the specified type, in this case, String, and provides type safety during compile-time checks.

True. In order for a minimum spanning tree to exist in a weighted and undirected graph, there must be a path connecting all the vertices.

This is because a minimum spanning tree is a tree that spans all the vertices and has the minimum possible total edge weight. If there is no path between two vertices, then it is impossible to create a tree that spans all the vertices and includes those two vertices. Therefore, no minimum spanning tree can exist for the graph.
Furthermore, it is important to note that the converse of this statement is also true. If a minimum spanning tree exists for a weighted and undirected graph, then there must be a path connecting all the vertices. This is because a minimum spanning tree spans all the vertices and includes the minimum possible total edge weight, so it necessarily includes all the edges that connect the vertices.

Option(D), the output of the statement is "1.2e+03", where the "1.2" corresponds to the first digit and the digit after the decimal point (i.e., "12"), and the "+03" corresponds to the exponent.

The statement System.out.printf("%3.1e", 1234.56) outputs "1.2e+03". This is because the %3.1e format specifier formats the floating-point number (1234.56) in scientific notation with one digit after the decimal point and three digits before the decimal point. The "e" in the format specifier stands for exponent. The number 1234.56 is represented as 1.23456e+03 in scientific notation, where the exponent is +03 (i.e., multiplied by 10^3). Therefore, the output of the statement is "1.2e+03", where the "1.2" corresponds to the first digit and the digit after the decimal point (i.e., "12"), and the "+03" corresponds to the exponent.
Note that the statement uses System.out.printf instead of System.out.print. The former is a method that allows for formatted output, while the latter simply prints the value of the expression inside the parentheses.
