![]() ![]() Check palindrome: We can use the substring in Java method to check if the given string is palindrome or not, i.e. Thus the length of the substring is endIndex-beginIndex. using substring method to extract substring Returns a substring starting from specified beginIndex till the character present at endIndex 1. Java code to demonstrate the application of substring method For instance, if you want to extract the last name from a given name or extract the digits after the decimal point from a string containing digits both before and after the point. The substring in Java method is used in many applications, including suffix and prefix extraction. If the startIndex is valid, the function creates a new string object with the specified range of characters from the original string object. If the startIndex is 0, the function returns the original string object. If the startIndex is less than 0 or greater than the length of the original string, a StringIndexOutOfBoundsException is thrown. However, this does not go out of bounds because of the substring() up to but not including use of the. The function first checks whether the startIndex is valid. The 5 is one more than the index of the last char. In the first implementation, the function takes only one parameter, startIndex. Here's an example program that uses the substring() method in Java, including some exception handling and corner cases: Use the charAt() method to get a character at a particular index from a String object. Some Exception Handling and Corner Cases Programs in Java The resulting substring is then assigned to the substrate variable and printed to the console. This means that the new substring will start at index 6 (which is the letter 'W' in "World") and end at index 11 (which is the last letter 'd' in "World"). In this example, the substring() method is called on the str string with parameters 6 and 11. String str = "Hello World" String substr = str.substring(6, 11) (substr) // Output: "World" It returns a new string containing the original string's characters from the begIndex (inclusive) up to the endIndex (exclusive). The Java substring(begIndex, endIndex) method extracts a portion of a given string. String str = "Hello, World!" String substr = str.substring(7, 12) To do this, we may utilize the substring() technique as seen below: ![]() Assume we have a string "Hello, World!" and wish to extract the substring "World". Let's look at an example to see how the substring() method functions. ![]() How Does the Method of Substring() Operate? ![]()
