We'll be using thefind()method in combination withstart()to check if ourMatcherinstance begins with a given String: publicstaticbooleanstartsWithSubstring(String text, String keyword){ String inputString = text.toLowerCase(); String subString = keyword.toLowerCase();// We compile the regular e...

4. String.startsWith() Method The startsWith() method can also be used for a more specific use-case where you want to check if a string starts with a given substring. This method returns a boolean value true if this string begins with the specified string, otherwise false. The following...
Write a Java program that matches a string with a 'p' followed by anything ending in 'q'. Sample Solution: Java Code: importjava.util.Scanner;publicclasstest{publicstaticvoidmain(String[]args){System.out.println(validate("phkuyrt"));System.out.println(validate("pq"));System.out.println(...
Java String startsWith() method Examples There are two variations of starsWith() method. boolean startsWith(String str): It returns true if the String str is a prefix of the String. boolean startsWith(String str, index fromIndex): It returns true if the String begins with str, it starts...
Firstly, we check if the string is null by comparing it with the value null using the == operator. If the string is indeed null, it means it is empty as well, and we can consider it as such. If the string is not null, we proceed to check its length using the length() method....
As you can see from the above example, endsWith() takes case (lower case and upper case) into consideration. If you need to check whether the string begins with the specified string or not, use the Java String startsWith() method.Previous...

If you are writing a MASM program to work with another high-level language, you should use the same memory model for both. Here is an example of a simple MASM program that displays a text string (“This is a simple MASM program”) on the screen using DOS function 09h: Sign in to ...
