Assume the following variables have been declared and given values as shown:
int i = 2345;
double m = 67.8;
What will be printed by the statement below?
System.out.printf("Values are %10d and %7.2f", i, j);
A)Values are 2345 and 67.8
B)Values are 2345 and 67.80
C)Values are %10d and %7.2f 2345 67.8
D)Values are %10d and %7.2f i j

The format specifier %10d in the printf statement specifies that the integer i should be printed in a field of width 10. The value is right-justified in this field, so any empty spaces are added to its left. Since the integer i has four digits, it will take up four spaces, and therefore six spaces will be added to its left.

The format specifier %7.2f specifies that the double m should be printed in a field of width 7, with two digits after the decimal point. The value is also right-justified, so any empty spaces are added to its left. Since the double m has three digits before the decimal point, it will take up four spaces, and therefore three spaces will be added to its left.

Therefore, the output will be "Values are 2345 and 67.80".
