JAVA

pre-increment vs post-increment

++x (pre-increment) means "increment the variable; the value of the expression is the final value"
x++ (post-increment) means "remember the original value, then increment the variable; the value of the expression is the original value"

pre increment and post increments

int x =0;
// POST increments: increments after it prints x or stmt  
System.out.println("Hello World"+ x++); // 0 
System.out.println("Hello World"+ x); // 1

// PRE increments: increments before it prints x or stmt  
System.out.println("Hello World"+ ++x); // 1
System.out.println("Hello World"+ x); // 1

pre increment and post increment

Pre-increment (++i) − Before assigning the value to the variable, the value is 
incremented by one.

Post-increment (i++) − After assigning the value to the variable, the value is 
incremented.
