What will be printed by the following code: System.out.println("4 * 4" + 12);?

The code provided uses string concatenation to combine the components within the println method. In this case, "4 * 4" is a string that will remain as it is, and 12 is represented as a number. When these elements are combined with the + operator, the string is appended to the number.

In Java, when you concatenate a string with other types (such as an integer), the integer is converted to its string representation. Here, the string "4 * 4" is followed directly by 12, leading to the final output of the string "4 * 412". There is no mathematical evaluation taking place; instead, it treats the "4 * 4" as a literal string and appends 12 to it directly.

Thus, the printed output will be 4 * 412, as the string representation of the number gets attached to the string, creating a single continuous string in the output.
