19+ practice questions focused on Java Basics and Syntax — one of the most tested topics on the Oracle Java Foundations 1Z0-811 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Java Basics and Syntax PracticeA developer writes the following code: int x = 5; System.out.println(x++); What is the output?
Explanation: The expression `x++` is a post-increment operator, which returns the current value of `x` (5) before incrementing it. Therefore, `System.out.println(x++)` prints 5, and then `x` becomes 6. Option B is correct because the output is the original value of `x`.
A team decides to use a single Java source file for a small application. Which statement is true about the file structure?
Explanation: Option C is correct because in Java, when a source file contains a public class, the file name must exactly match the public class name, including case sensitivity. This is a fundamental rule enforced by the Java compiler to ensure proper class loading and package structure. The file can have at most one public top-level class, and that class name determines the file name.
Given the code: String s1 = "Java"; String s2 = new String("Java"); if (s1 == s2) { System.out.print("Equal"); } else { System.out.print("Not Equal"); } What is the output?
Explanation: Option D is correct because the == operator compares object references, not the actual string content. s1 is a string literal stored in the string pool, while s2 is a new String object created on the heap, so they refer to different memory locations, making the comparison false and printing 'Not Equal'.
Which primitive data type should be used to store a single character?
Explanation: Option C is correct because the `char` primitive data type in Java is specifically designed to store a single 16-bit Unicode character, ranging from '\u0000' (0) to '\uffff' (65,535). It can represent any character in the Unicode standard, including letters, digits, and symbols, making it the appropriate choice for a single character value.
A method is declared as: public static void main(String[] args) { }. Which statement is true?
Explanation: Option C is correct because the `static` modifier in the method signature means the method belongs to the class itself, not to any instance. Therefore, it can be invoked using the class name (e.g., `ClassName.main(args)`) without creating an object of the class. This is a fundamental characteristic of static methods in Java.
