Question

Summary in this lab, you declare and initialize constants in a java program. the program file named , calculates your age in the year 2050. instructions declare a constant named year, and initialize year with the value 2050. edit the following statement so it uses the constant named year: newage = currentage (2050 − currentyear); edit the following statement so it uses the constant named year: .println("i will be" newage "in 2050."); execute the program.

Answer 1

To use a constant named YEAR with the value 2050 in a Java program, declare it with the final keyword and use it in calculations and print statements instead of the literal year value for future age calculation.

Step-by-step explanation:

To declare and initialize a constant in a Java program for the purpose of calculating your age in the future, you would first define the constant using the final keyword, followed by the data type, the constant's name, and then its value. In this lab, you are asked to declare a constant named YEAR and initialize it with the value 2050 to calculate your age in that year.

The statement to calculate the new age should be edited to use the constant rather than the literal value of the year. This can be done by replacing 2050 with the constant's name in the statement. The adjusted calculation would be newAge = currentAge + (YEAR - currentYear). Similarly, the print statement should also use the constant by editing it to be System.out.println("I will be " + newAge + " in " + YEAR + ".").

Remember to declare the constant at the beginning of your program so that it can be used throughout. Once these changes are made, executing the program will display your age in the year 2050.
