Question

// This program calculates your age in the year 2050.
// Input: None.
// Output: Your current age followed by your age in 2050.

public class NewAge2
{
public static void main(String args[])
{
int currentAge = 25;
int newAge;
int currentYear = 2014;
// Declare a constant named YEAR and initialize it to 2050

// Edit this statement so that it uses the constant named YEAR.
newAge = currentAge + (2050 - currentYear);

System.out.println("My Current Age is " + currentAge);
// Edit this output statement so that is uses the constant named YEAR.
System.out.println("I will be " + newAge + " in 2050.");

System.exit(0);
}
}

1. Decalre a constant named YEAR, and initialize YEAR with the value 2050.

2. edit the following statement so it uses the constant names YEAR:

newAge = currentAge + (2050 - currentYear);

3. edit the following statement so it uses the constant names YEAR:

system.out.println("I will be" + newAge + "in 2050.");

4. Compile source code NewAge2.java

       int currentAge = 25;
       int newAge;
       int currentYear = 2014;
       // Declare a constant named YEAR and initialize it to 2050

      // Edit this statement so that it uses the constant named YEAR.
       newAge = currentAge + (constant - currentYear);

      System.out.println("My Current Age is " + currentAge);
       // Edit this output statement so that is uses the constant named YEAR.
       System.out.println("I will be " + newAge + " in "+ constant);

      System.exit(0);
    }
}
