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

A number can be multiplied by 2 using bitwise operators. This is done by using the left shift operator and shifting the bits left by 1. This results in double the previous number.A program that demonstrates multiplication of a number by 2 using bitwise operators is given as follows.Example Live Demousing System; namespace BitwiseDemo { class Example { static void Main(string[] args) { int num = 25, result; result = num
Let’s say the following is our string.String str = "Java is a programming language. James Gosling developed it.";We will now see how to split a string using the split() method. Include the delimiter as the parameter.String[] strSplit = str.split("\.");Above, we have split the string with dot as you can see under the split methods parameter.The following is an example.Example Live Demopublic class Demo { public static void main(String[] args) { String str = "Java is a programming language. James Gosling developed it."; System.out.println("String: "+str); String[] strSplit = str.split("\."); ... Read More
