Conditionals

If ... else

if (expr) {
    statements;
}
else if (expr) {
    statements;
}
else {
    statements;
}

Switch statement

switch (expr) {
    case VALUE: 
        statements;
        break;
    case VALUE: 
        statements;
        break;
    default:
        statements;
        break;
}

• The expr value must be a byte, short, int, or char.
• Each case value must be a unique literal value; variables cannot be used.
  
• Add a break statement to the end of the last case as a precautionary measure, in case additional cases are added later.
• Braces are required.
