Introduction to Computer Programming A Java Program
Forward iterations only: Use the “for-each” loop only for forward looping and that too in single steps. Compatibility: If you need your code to be compatible with versions before Java 5, you might want to go for the regular for loop.... Essentially i'm making a shopping application in blueJ and I've stumbled across a problem. I've made and If statement which allows the user to 1. shop 2. check basket 3. go to checkout and when I enter 1 to go through my shopping and add my stuff to the shopping list, I cant seem to exit the while loop within.

Thus the body of this for loop gets executed and i*j (which is 14*1) i.e. 14 gets on the screen and then j++ increases the value of j by 1, making its value equal to 2. Again the condition of the loop gets satisfied since the value of j is 2 this time ( 2 is less than 10 ).... Loop statements in Java In previous articles you learned about variables and types and now it's time to speak about control statements in Java. There are several types of statements in Java, which are useful for repeating things.

java How do I leave a while loop which is within an if
Java contains a continue command which can be used inside Java while (and for) loops. The continue command is placed inside the body of the while loop. When the continue command is met, the Java Virtual Machine jumps to the next iteration of the loop without executing more of the while loop body.... A while loop is a control flow statement that allows us to run a piece of code multiple times. Like loops in general, a while loop can be used to repeat an action as long as a condition is met.

The init code runs once to set things up at the very start of the loop. Typically, this looks like "int i = 0", declaring a variable to use for the counting, and setting its start value. The variable exists only within the loop (down through the } of the body).

- You can write any piece of code inside a for loop that you can write normally. Loop means if you are doing the same stuff repetitively then you can reduce the code length by using the looping statement.
