Java enhanced for/in

Hi all, How does the for/in works?!

I have the following small example i'm not understanding the structure:

// find minimum grade

publicint getMinimum()

{

// assume first element of grades array is smallest

int lowGrade = grades[ 0 ][ 0 ];

// loop through rows of grades array

for (int studentGrades[] : grades )

{

// loop through columns of current row

for (int grade : studentGrades )

{

// if grade less than lowGrade, assign it to lowGrade

if ( grade < lowGrade )

lowGrade = grade;

}// end inner for

}// end outer for

return lowGrade;// return lowest grade

}// end method getMinimum

My question is what do we use in it?
