Compound Assignment

int score = 100;
score = score + 10;  // add 10 to score
score = score - 5;   // subtract 5 from score
score = score * 2;   // double the score

int score = 100;
score += 10;   // score is now 110
score -= 5;    // score is now 105
score *= 2;    // score is now 210
score /= 3;    // score is now 70 (integer division!)
score %= 6;    // score is now 4 (70 % 6 = 4)

int count = 5;
count++;    // count is now 6
count++;    // count is now 7
count--;    // count is now 6

int a = 5;
int b = a++;   // b = 5 (a's OLD value), then a becomes 6

int c = 5;
int d = ++c;   // c becomes 6 FIRST, then d = 6

int x = 10;
int y = 3;
x += y;       // x = 10 + 3 = 13
y *= x;       // y = 3 * 13 = 39
x -= 5;       // x = 13 - 5 = 8
y %= x;       // y = 39 % 8 = 7
System.out.println(x + " " + y);  // Output: "8 7"

String message = "Hello";
message += " World";      // message is now "Hello World"
message += "!";           // message is now "Hello World!"
System.out.println(message);  // Output: "Hello World!"
