Let’s say we have the following string.String str = "{Java is a programming language} {James Gosling developed it.}";Above, the string is enclosed with parentheses. We can split a string with these parentheses using the split() method.String[] strSplit = str.split("[{}]");The following is an example.Example Live Demopublic class Demo { public static void main(String[] args) throws Exception { String str = "{Java is a programming language} {James Gosling developed it.}"; String[] strSplit = str.split("[{}]"); System.out.println("Splitting String..."); for (int i = 0; i < strSplit.length; i++) System.out.println(strSplit[i]); ...

Merge Sort is a sorting algorithm that uses the divide and conquer method. It divides the array into two parts and then calls itself for each of these two parts. This process is continued until the array is sorted.A program that demonstrates merge sort in C# is given as follows −Example Live Demousing System; namespace QuickSortDemo { class Example { static public void merge(int[] arr, int p, int q, int r) { int i, j, k; int n1 = q - p + 1; int ...

We have the following string with a separator.String str = "Tom-Hanks";We want the substring after the first occurrence of the separator i.e.HanksFor that, first you need to get the index of the separator and then using the substring() method get, the substring after the separator.String separator ="-"; int sepPos = str.indexOf(separator); System.out.println("Substring after separator = "+str.substring(sepPos + separator.length()));The following is an example.Example Live Demopublic class Demo { public static void main(String[] args) { String str = "Tom-Hanks"; String separator ="-"; int sepPos = str.indexOf(separator); if (sepPos == -1) ...

We have the following string with two separators.String str = "Tom-Hank-s";We want the index of the first occurrence of the separator.For that, you need to get the index of the separator using indexOf()String separator ="-"; int sepPos = str.indexOf(separator);The following is an example.Example Live Demopublic class Demo { public static void main(String[] args) { String str = "Tom-Hank-s"; String separator ="-"; System.out.println("String: "+str); int sepPos = str.indexOf(separator); System.out.println("Separator's first occurrence: "+sepPos); } }OutputString: Tom-Hank-s Separator's first occurrence: 3
We have the following string with a separator.String str = "David-Warner";We want the substring before the last occurrence of a separator. Use the lastIndexOf() method.For that, you need to get the index of the separator using indexOf()String separator ="-"; int sepPos = str.lastIndexOf(separator); System.out.println("Substring before last separator = "+str.substring(0, sepPos));The following is an example.Example Live Demopublic class Demo { public static void main(String[] args) { String str = "David-Warner"; String separator ="-"; int sepPos = str.lastIndexOf(separator); if (sepPos == -1) { System.out.println(""); ...

Let’s say we have the following string.String str = "Learning never ends! Learning never stops!";In the above string, we need to find out how many times the substring “Learning” appears.For this, loop until the index is not equal to 1 and calculate.while ((index = str.indexOf(subString, index)) != -1) { subStrCount++; index = index + subString.length(); }The following is an example.Example Live Demopublic class Demo { public static void main(String[] args) { String str = "Learning never ends! Learning never stops!"; System.out.println("String: "+str); int subStrCount = 0; String subString ... Read More
