Explanation

String concatenation is left‑to‑right. The first print yields a space, then 7 and 2 become "72" surrounded by spaces. The second print concatenates "foo", 42 and 5 giving "foo425" plus a trailing space. The final println adds 42+44=86 to "foo" producing "86foo". Hence the output matches "72 foo425 86foo".
