Java - Nested Statements, Switch Statments, and Boolean Operators

Nesting:

Putting one coding structure inside of another coding structure.

Ex: if (condition) {
if ( condition) {
statements;
} else {
statements;
} else {
statements;
}

Boolean opperators:

AND = &&
OR = ||
NOT = !

Ex: if (root == 2 || root == -2) {
statements;
}

If statements with multiple boolean opperators:

These need brackets:

Ex: if ( time == 6.0 || (day.equals ("Sunday") && time == 11.0)) {

Switch statement:

Used to have the program make a descicion. The condition for a switch statement must be an integer expression.

int dayOfWeek = 4;
Ex: switch (dayOfWeek) {
case 6:
System.out.println("Today is saturday!");
break;
case 7:
System.out.println("Today is sunday!");
break;
default:
System.out.println("Looking forward to the weekend!");
}

*default statement will print if dayOfWeek is anything other than 6 or 7*
