Applied.It's important to store and use the return value of the replace() method if you want to work with the modified string.String replaceFirst()Similar to the Java.String.replace() method, this technique replaces the first substring of the string that has a match between the provided regular expression and the given replacement value.Identical to the Java.String.replace() operation, this method also returns a resulting string.Examples of String replace()public class upGrad { public static void main(String[] args) { String originalString1 = "upGrad"; String replacedString1 = originalString1.replace('u', 'U'); System.out.println("Example 1:"); System.out.println("Original string: " + originalString1); System.out.println("Replaced string: " + replacedString1); System.out.println(); String originalString2 = "upGrad"; String replacedString2 = originalString2.replace("Grad", "Skills"); System.out.println("Example 2:"); System.out.println("Original string: " + originalString2); System.out.println("Replaced string: " + replacedString2); System.out.println(); String originalString3 = "upGrad"; String replacedString3 = originalString3.replace("u", "U").replace("p", "P"); System.out.println("Example 3:"); System.out.println("Original string: " + originalString3); System.out.println("Replaced string: " + replacedString3); System.out.println(); String originalString4 = "upGrad"; String replacedString4 = originalString4.replaceAll("[aeiou]", "*"); System.out.println("Example 4:"); System.out.println("Original string: " + originalString4); System.out.println("Replaced string: " + replacedString4); }}Output:The above program demonstrates various examples of using Java's replace() method to replace characters or substrings within a string. Let's go through each example in detail:Example 1: Replacing a single characterIn this example, the original string upGrad is assigned to the originalString1 variable. The replace() method is then used to replace the character 'u' with 'U', resulting in the modified string UpGrad. The original and replaced strings are printed using System.out.println().Example 2: Replacing a substringIn this example, the original string upGrad is assigned to the originalString2 variable. The replace()

Method is used to replace the substring "Grad" with "Skills", resulting in the modified string upSkills. Like the previous example, original and replaced strings are printed using System.out.println().Example 3: Replacing multiple charactersIn this example, the original string upGrad is assigned to the originalString3 variable. Chaining multiple replace() methods is applied to replace the characters 'u' and 'p' with their uppercase counterparts, resulting in the modified string UpGrad. The original and replaced strings are then printed using System.out.println().Example 4: Replacing multiple characters using regexIn this example, the original string upGrad is assigned to the originalString4 variable. The replaceAll() method is used with a regular expression [aeiou] to match and replace all vowels with an asterisk (*), resulting in the modified string *pGr*d. Finally, the original and replaced strings are printed using System.out.println().replaceFirst() Methodpublic class upGrad { public static void main(String[] args) { String originalString5 = "upGrad"; String replacedString5 = originalString5.replaceFirst("a", "A"); System.out.println("replaceFirst Example:"); System.out.println("Original string: " + originalString5); System.out.println("Replaced string: " + replacedString5); }}This program begins by defining a class named upGrad. Inside the main method, a string variable originalString5 is declared and assigned the value "upGrad". This variable represents the original string on which the replacement operation will be performed.The replaceFirst() method is then used on originalString5 to replace the first occurrence of the substring "a" with the character "A". The resulting replaced string is stored in the variable replacedString5.Finally, to display the output, the program uses System.out.println() to print the heading "replaceFirst Example:". It then prints the original and
