Syntax
break;\ncontinue;Examples
Using break
Exiting a loop as soon as a target condition is found.
int[] numbers = {1, 3, 5, 8, 9, 12};
for (int num : numbers) {
if (num % 2 == 0) {
System.out.println("Found first even number: " + num);
break;
}
System.out.println(num + " is odd");
}Using continue
Skipping specific iterations while letting the loop continue.
for (int i = 1; i <= 10; i++) {
if (i % 2 != 0) {
continue; // skip odd numbers
}
System.out.println(i); // prints only even numbers
}Labeled break in Nested Loops
Using a label to break out of an outer loop directly from within an inner one.
outerLoop:
for (int i = 1; i <= 3; i++) {
for (int j = 1; j <= 3; j++) {
if (i == 2 && j == 2) {
break outerLoop; // exits BOTH loops, not just the inner one
}
System.out.println("i=" + i + ", j=" + j);
}
}Best practices
- Use break to stop a loop as soon as further iteration is pointless, avoiding wasted work
- Use labeled break/continue sparingly - they are powerful for nested loops but can make control flow harder to follow if overused
- Prefer restructuring logic into a separate method with an early return over deeply nested labeled breaks when possible
- Use continue to skip invalid items cleanly instead of wrapping the rest of the loop body in a large if block

Variables & Primitive Data Types
Java is a statically-typed language, meaning every variable must be declared with an explicit type before use, and that type cannot change afterward. Java has eight primitive types - byte, short, int, long, float, double, char, and boolean - which store simple values directly rather than references, making them fast and memory-efficient. Anything beyond primitives (String, arrays, custom classes) is a reference type instead.System.out.println / print / printf
System.out is Java's standard output stream, and it exposes three main methods for writing text to the console. println() prints its argument followed by a newline, print() prints without adding a newline, and printf() gives C-style formatted output using format specifiers like %d, %s, and %.2f for precise control over how values are displayed.Comments & Javadoc
Java supports single-line comments with //, multi-line comments with /* */, and a special documentation format called Javadoc, written as /** */. Javadoc comments support tags like @param, @return, and @throws, and can be processed by the javadoc tool to automatically generate HTML API documentation - the same format used for Java's own official standard library docs.Arithmetic & Assignment Operators
Java provides the standard arithmetic operators for numeric computation: +, -, *, / for division, and % for the remainder (modulus). It also has compound assignment operators (+=, -=, etc.) that combine an operation with assignment, along with increment (++) and decrement (--) operators in both prefix and postfix forms, which subtly differ in when the value is updated relative to being used.
