Question

Assume the following variable declaration exists in a program:

double number = 123.456
Write a statement that uses System.out.printf to display the value of the number variable padded with leading zeros, in a field that is eight spaces wide, rounded to one decimal place. (Do not use comma separators).

Answer 1

Step-by-step explanation:

Answer:

System.out.printf("%08.1f", number);

Step-by-step explanation:

The complete lines of code is

public class MyClass {

public static void main(String args[]) {

double number = 123.456;

System.out.printf("%08.1f", number);

}

}

This line declares and initializes number to 123.456

double number = 123.456;

The second statement is analyzed as thus:

System.out.printf -> Used to print floating point numbers

"%08.1f" ->

%08 implies that the field is 8 field wide and all leading empty spaces would be replaced with 0.

.1f implies that the number be approximated to 1 decimal place

Answer 2

System.out.printf("%08.1f", number);

Step-by-step explanation:

The complete lines of code is

public class MyClass {

public static void main(String args[]) {

double number = 123.456;

System.out.printf("%08.1f", number);

}

}

This line declares and initializes number to 123.456

double number = 123.456;

The second statement is analyzed as thus:

System.out.printf -> Used to print floating point numbers

"%08.1f" ->

%08 implies that the field is 8 field wide and all leading empty spaces would be replaced with 0.

.1f implies that the number be approximated to 1 decimal place

number -> The variable to be printed
