How To Use For In Java

Tanggal : 15 Feb 2023, Category : Pemprograman Website, Create By : admin

In Java, the for loop has a slightly different syntax than in JavaScript. The for loop in Java can be used with an enhanced version called the "for-each" loop, which is designed to iterate over arrays and collections. Here's how to use the for and for-each loops in Java:

Using a for loop:

for (int i = 0; i < 10; i++) {
System.out.println(i);
}

In this code, the for loop runs 10 times, with the variable i taking on the values 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 in each iteration. The loop body prints the value of i to the console in each iteration.

Using a for-each loop:

int[] numbers = {1, 2, 3, 4, 5};
for (int num : numbers) {
System.out.println(num);
}

In this code, the for-each loop runs for each element of the numbers array. The loop body prints the value of each element to the console in each iteration.

The syntax for the for-each loop is as follows:

for (datatype variable : collection) {
// Loop body
}

In this syntax, datatype is the type of the elements in the collection, variable is the variable that will hold each element of the collection in each iteration, and collection is the array or collection being iterated over.

The for-each loop is a more concise and readable way to iterate over arrays and collections in Java, and is especially useful when you don't need to keep track of the index of each element.
