Chapter 2: Basic Syntax - Java Quick Tutorial

1. Variables

var count = 42;
final String APP = "demo";

var infers the type from the initializer (Java 10+).

int[] nums = {1, 2, 3};
for (var n : nums) {
    System.out.println(n);
}

String sql = """
    SELECT * FROM users
    WHERE active = true
    """;

Static typing with var sugar; checked exceptions; multi-line strings without concatenation noise.
