Java loops

Question

Is there any particular difference in java in looping statements?

Answer 1

you can either use a for loop that iterates a defined number of times.

for (int i = 0 ; i < 10 ; i++) { instructions }

will iterate 10 times

a while that iterates as long as your condition is true

while(condition) { instructions }

will iterate as long as condition==true

a do-while, that is a while, but it iterates at least once

do{ instructions }
while(condition)

will iterate as long as condition==true, but will anyway iterate at least once

and a for each, which is a particular type of for, that does you operation for every element in a certain array/collection

Integer[] MyArr = new Arr[10]
for ( Integer i : MyArr ) { instructions }

will execute the instructions on every element of MyArr

Answer 2

do{
...
}while(...)

will be executed at least once unlike

while(...){
...
}

and with a for loop, you can don't need to initialize the variables and conditions before

Answer 3

do you mean differences between Java and other languages or between different cycles in Java?

Answer 4

yes

Answer 5

FOR LOOP:we use for loop when we know the starting and end condition
for eg :we print even numbers from 0 to 10
for(i=0;i,<=10;i=i+2)
{
System.out.println(i);
}
WHILE LOOP: we use while loop we don't know the exactly how many times the loop executed it stop its execution when condition is false.if the condition is false it execute the statements below while loop
example:
int x=50;
while(x>100)
{
System.out.println(x);
x++;
}
System.out.println("hi");
}
