For loops are used when no of times to implement the statements is refer to the programmer. b. while Loops: While loop is used if certain statements require being implemented regularly until a condition is satisfied. The condition is tested first before implementation of statements in while loops. c. Do While Loops: Do while loop is similar to while loop with an only difference which condition is examined after implementation of statement blocks. Thus in do while loop case, statements are implemented at least once. 6. What is a singleton class?

When you are asked to explain Break and Continue concept in Java Interview Questions for Freshers, I suggest you to give examples to attract the interviewer. Break and continue statements are the two main keywords used in loops. When a break keyword is used in a loop, instantly the loop is broken while when continue keyword is used, the current iteration is broken and the loop continues with the next iteration. When counter reaches 4, loop is broken in the below example. For (counter=0; counter<10; counter++) System.out.println(counter); if (counter==4) { break; }} When counter reaches 4, loop just jumps to the next iteration in the below example and after the continue keyword any statements are skipped for the current iteration. for (counter=0; counter<10; counter++) system.out.println(counter); if (counter==4) { continue; } system.out.println(“This will not get printed when counter is 4”); } 8. What is known as infinite loop? Explain how infinite loop is declared? An infinite loop runs infinitely and without any condition. An infinite loop may be broken by explaining any breaking logic in the statements blocks body. Infinite loop is proclaimed as follows for (;;) { // Statements to execute // Add any loop breaking logic } 9. What is known as a final keyword in Java? Give an example A constant is proclaimed using the keyword final in Java. The value may be assigned once and after the assignment, the value of a constant cannot be changed. A constant with the name const_val has been assigned and declared a value in the below example: Private Final int const_val=100 It cannot be overridden by the subclasses if a method is declared as final. This method is considered to be faster than any other method because they have been resolved at the compiled time. It can’t be subclassed, when a class is declared as final. E.g., integer, string, and other wrapper classes. 10. Explain the difference between float and double variables in Java? Float always takes about 4 bytes in memory while double takes about 8 bytes in memory in Java. The float is said to be single precision floating point decimal number and the double is the double precision decimal number. 11. How will you generate random numbers in Java?
