what is String... in java code example
Example 1: string method example in java
public class StringMethodsDemo {
public static void main(String[] args) {
String targetString = "Java is fun to learn";
String s1= "JAVA";
String s2= "Java";
String s3 = " Hello Java ";
System.out.println("Char at index 2(third position): " + targetString.charAt(2));
System.out.println("After Concat: "+ targetString.concat("-Enjoy-"));
System.out.println("Checking equals ignoring case: " +s2.equalsIgnoreCase(s1));
System.out.println("Checking equals with case: " +s2.equals(s1));
System.out.println("Checking Length: "+ targetString.length());
System.out.println("Replace function: "+ targetString.replace("fun", "easy"));
System.out.println("SubString of targetString: "+ targetString.substring(8));
System.out.println("SubString of targetString: "+ targetString.substring(8, 12));
System.out.println("Converting to lower case: "+ targetString.toLowerCase());
System.out.println("Converting to upper case: "+ targetString.toUpperCase());
System.out.println("Triming string: " + s3.trim());
System.out.println("searching s1 in targetString: " + targetString.contains(s1));
System.out.println("searching s2 in targetString: " + targetString.contains(s2));
char [] charArray = s2.toCharArray();
System.out.println("Size of char array: " + charArray.length);
System.out.println("Printing last element of array: " + charArray[3]);
}
}

Example 3: string method example in java
