Answer

In Java, you can use the `substring` method to get the first N characters from a string.

✐ Examples

1 First 5 Characters of "Hello World" String

In this example,

We create a variable named str with a string value of "Hello World".
We use the substring method with str, 0 as the start index, and 5 as the end index to get the first 5 characters.
Finally, we print the first 5 characters.

Java Program

// First 5 Characters of "Hello World" String
public class Main {
    public static void main(String[] args) {
        String str = "Hello World";
        String first5Chars = str.substring(0, 5);
        System.out.println("First 5 characters of the string are: " + first5Chars);
    }
}

Output

First 5 characters of the string are: Hello

2 First 3 Characters of "apple" String

In this example,

We create a variable named str with a string value of "apple".
We use the substring method with str, 0 as the start index, and 3 as the end index to get the first 3 characters.
Finally, we print the first 3 characters.

Java Program

// First 3 Characters of "apple" String
public class Main {
    public static void main(String[] args) {
        String str = "apple";
        String first3Chars = str.substring(0, 3);
