System.out.printf无法与Integer一起使用

Question

When I type this part of code below it gives me an error message next to the System.out.printf line.

It tells me that I should replace the Integer type for i into Object[] .

However in the tutorial I am following the part below works and doesn't give any error messages. So is there something i did wrong here or what is the correct type then?

    for(int i=0; i < 5;i = i + 1) {
        System.out.printf("The value of i is: %d\n", i);
    }

Answer 1

You can get, and print its value, this way:

for(int i=0; i < 5;i = i + 1) {
    System.out.printf("The value of i is: %d\n", Integer.valueOf(i));
}
