What is the output of the following piece of Java code?

int id = 4; 
double grossPay = 81.475;
String jobType = "Intern";
System.out.printf("Id: %d, Type: %s, Amount:%.2f", id,grossPay,jobType);

Select one:

Error

Id: 4, Type: Intern, Amount: $81.475

Id: 4, Type: $81.475, Amount: Intern

Id: 4, Type: $81.48, Amount:Intern

Id: 4, Type: Intern, Amount: $81.48

Expert Solution

Output: Error

There is a Runtime error in the code, not a compile-time error.

Runtime Error :

Exception in thread "main" java.util.IllegalFormatConversionException: f != java.lang.String.

System.out.printf("Id: %d, Type: %s, Amount:%.2f", id,grossPay,jobType);

In this statement, for grossPay, %s is used as the format specifier, but grossPay is double so it has to be %f .

Correction:

System.out.printf("Id: %d, Type: %.2f, Amount:%s", id,grossPay,jobType);

Program:

class Output
{
public static void main(String args[])
{
int id = 4;
double grossPay = 81.475;
String jobType = "Intern";
System.out.printf("Id: %d, Type: %.2f, Amount:%s", id,grossPay,jobType);
}
}
