Logical Operators

The If-Else Statement

if (<condition1>) { 
    <body1> 
} else if (<condition2>) {
    <body2>
} else {
    <body3>
}

Tip

Curly braces are not required for one-line if-else statements

Switch Statements

switch (<expression>) {
    case <case1>: <expr> 
    case <case2>: <expr>
    default: <expr>

Tip

Java will jump to the first matching case, and will execute blocks after matching case. To prevent execution of following cases, use break at the end of the block.

Equality

The == sign is the default way to check for equality. This is equivalent to the .equals(obj) method, which is built-in to all classes (all objects extend the Object superclass)
