Loops in Java

• for loop.
• Enhanced for loop.
• while loop.
• do-while loop.

Java has three types of loops i.e. the for loop, the while loop, and the do-while loop. for and while loops are entry-controlled loops whereas do-while loop is an exit-controlled loop.

for Loop:

• The for loop is used when you know the number of iterations in advance.
• It consists of an initialization statement, a condition for termination, and an update statement, all separated by semicolons.

while Loop:

• • The while loop repeatedly executes a block of code as long as a given condition is true.
  • It checks the condition before each iteration.

do-while Loop:

• • • The do-while loop is similar to the while loop, but it checks the condition after executing the block of code. This guarantees that the code block will be executed at least once.

enhanced for Loop (for-each Loop):

• • • • The enhanced for loop is used to iterate over elements in an array or other iterable collections.
      • It simplifies the syntax for iterating over elements without needing explicit indexing.
