Loops in Java

Loops in java are very simple, as are all other loops in the other languages. There are three types of loops Do While, While, and For. First let’s look at the Do While loop.

Starting from the beginning you set up the class, then the method. Next declare the variable that you start with. Then the Do statement starts, it prints out “The number is” then the variable that you started with, and ends with a count up method for the starting variable. At the end of the loop the while statement indicates an if statement that when your starting variable is less than or equal to 100, then it stops the loop.

This second type of loop is called a For loop.

Starting off you set up the class and a method like the Do While loop. Now inside the for method contains a declared variable, then the conditional (for example if “i” is less than or equal to 10 then the loop will end), next the i++ is the increment of +1 to the variable i. For every time this loop executes the output should be “The number is” then the variable.

Now last but not least the While loop.

One of the simplest loop is the While loop. First make the class and method. Next you set up variable like the Do_While. Then the while statement declares if “i” is less than or equal to 10. The output would be “The number is” plus the variable, then the variable increases by one(using the i++ statement).
