The answer is : Option C. Compiling time error because "methodB" is not defined in Class A
The method 'methodB()' is available in Class B. We wont get this error, if Class A extends Class B.
What is the output of following program: public class Test{ public static void main(String[] args) {...
1. What is the output when you run printIn()? public static void main(String[] args) { if (true) { int num = 1; if (num > 0) { num++; } } int num = 1; addOne(num); num = num - 1 System.out.println(num); } public void addOne(int num) { num = num + 1; } 2. When creating an array for primitive data types, the default values are: a. Numeric type b. Char type c. Boolean type d. String type e. Float...
what is output public static void main(String args) Scanner keyboard new Scanner(System.in); int u 14; int w 0; int x; int y 5; float z = 6.1 System.out.print("Enter y: "); x keyboard.nextint); System.out.println('y'); System.out.println(x); System.out.println(w*3); x- x+(int)z; System.out.println(x); 0 System.out.println(u); System.out.,println(u); System.out.println"x In" + y); System.out.print(y + z); ) liclosing main method 1 liclosing class header
What output is produced by the following program? public class MysteryNums public static void main(String[] args) - int x = 12; int y = x - 3; 3, sentence (y, x + y); . public static void sentence (int numi, int num2) { 4: System.out.println(num1 + " + num2);
Analyze the following code: public class Test { private int t; public static void main(String[] args) { int x; System.out.println(t); } } The variable t is private and therefore cannot be accessed in the main method. The program compiles and runs fine. t is non-static and it cannot be referenced in a static context in the main method. The variablet is not initialized and therefore causes errors. The variable x is not initialized and therefore causes errors.
Consider the following codes: public class TestThread extends Thread { public static void main(String[] args) { TestThread thread = new TestThread(); } @Override public void run() { printMyName(); } private void printMyName() { System.out.println("Thread is running"); } } Test Stem / Question Choices 1: What method should you invoke to start the thread TestThread? A: start() B: run() C: No. Thread will run automatically when executed. D: TestThread is not...

1. Look at the following pseudocode algorithm. package javaapplication292 public class JavaApplication292 ( public static void main(StringlI args) recFun(258); public static void recFun( int x) if (x > 10) recFun (x/10); System.out. printIn( x % 10 ); else System.out.println(x); What is the output of the following statements? a. recFun(258); b. recFun (7);
