OOPs in Java refers to Object-Oriented Programming concepts like classes, objects, inheritance, polymorphism, and encapsulation. Looping in Java refers to repeating a block of code multiple times using loops like for, while, and do-while.
OOPs concepts in Java include classes, objects, inheritance, polymorphism, and encapsulation.
Looping in Java can be achieved using for, while, and do-while loops.
Example: for(int i=0;
The while loop executes a block of code as long as the specified condition is true, while the do while loop executes the block of code once before checking the condition.
While loop syntax: while (condition) { // code block to be executed }
Do while loop syntax: do { // code block to be executed } while (condition);
The do while loop will always execute the code block at least once, even if the condition is false.
