FOR EACH
LOOP
Hey guys, we are back with another blog today and in this we
are going to talk about ‘for each loops’ first and then we’ll see how much it
differs from an actual ‘for loop’.
For each loop:
For each loop in java in executes the statements inside the
for loop according to the number of elements present inside the loop rather
than pre-mentioning how long the loop will run and under what condition it will
continue to.
Syntax:
for(type variableName : arrayName) {
//CODE
}
So in ‘for each loop’ we just mention the type of the value
inside an array and then the variable name that we could use inside the code to
play with the actual values inside the array, followed by a colon and the array
name. And this loop will run until and unless the loop has run for each element
inside the array. So let’s see an actual implementation of for each loop.
public class Coding_Winds {
public static void main(String[] args) {
String fruits[] = {"banana", "mangoes","apple", "grapes"};
for(String x : fruits) {
System.out.println(x);
}
}
}
Output: banana
mangoes
apple
grapes
So as we can see that in this loop we don’t care about the condition or
how long the loop will run, it is designed to run for each element of the loop.
FOR EACH LOOP VS FOR LOOP
Now let’s see how it is different from a for loop:
