Example
int a = 10, b = 3;
System.out.println(a + b);
System.out.println(a / b); // integer division
System.out.println(a % b); // remainder
System.out.println(a > b && b > 0);
System.out.println(++a); // pre-increment
System.out.println(--a);
int max = (a > b) ? a : b;
System.out.println("Max: " + max);13

++a increments first, then uses the value; a++ uses the value first, then increments.Track your progress through the Java course
