Hello! Quick question about printing ints

Question

int c = 2;
int b = 3;
int a = c * b;

System.out.print("a=" + a); output a = 6

!!! Why do I have to set ("a="+a) vs just print(a) ??

Ive searched a bunch of documentation but found no coverage on the matter....

Answer 1

System.out.print("a=" + a); //prints "a=6"
System.out.print(a); //prints "6"
