Use the indexOf() method to search for a substring from a given position.Let’s say the following is our string.String myStr = " pqrstuvwxyzpqrst";Searching for the substring “pqrs” in the string. We are beginning the index from 3 for our search.int begnIndex = 3; strLastIndex = myStr.indexOf("pqrs", begnIndex);Example Live Demopublic class Demo {     ... Read More

Use the System.getProperty() method in Java to get the Operating System name.It’s syntax is −String getProperty(String key)Above, the key is the name of the system property. Since, we want the OS name, therefore we will add the key as −os.nameExample Live Demopublic class Demo {     public static void main(String[] args) {        System.out.print("Operating System: "); ...

To compare string for equality in Java, use the equals() method. Let us see some examples wherein we have checked for same as well as different string values.Example Live Demopublic class Demo {     public static void main(String[] args) {        String one = "x";        String two = "x";        if(one.equals(two)) {           ...
