You can compare two strings using either equals() method or compareTo() method.Where, The equals() method compares this string to the specified object.The compareTo() method compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings.These two methods compare the given strings with respective to Case i.e. String with the different case are treated differently.ExampleFollowing example demonstrates the comparison of two strings using the equals() method.Live Demopublic class Sample{ public static void main(String args[]) { String str = "Hello World"; String anotherString = "hello world"; ...

This class concatenates the specified string to the end of this string.ExampleLive Demopublic class Test { public static void main(String args[]){ String str1 = "Krishna"; String str2 = "Kasyap"; System.out.println(str1.concat(str2)); } }OutputkrishnaKasyap

Java String class provides different comparison methods namely:The compareTo() methodThis method compares two Strings lexicographically. This method returns a negative integer if current String object lexicographically precedes the argument string. a positive integer if current String object lexicographically follows the argument true when the strings are equal.Exampleimport java.lang.*; public class StringDemo { public static void main(String[] args) { String str1 = "tutorials", str2 = "point"; // comparing str1 and str2 int retval = str1.compareTo(str2); // prints the return value of the comparison ...

Following is an example which compares Strings and portion of strings in Java? Explain with an example.ExampleLive Demopublic class StringDemo { public static void main(String[] args) { String str1 = "tutorials point"; String str2 = str1.substring(10); int result = str1.compareTo(str2); // prints the return value of the comparison if (result < 0) { System.out.println("str1 is greater than str2"); }else if (result == 0) { System.out.println("str1 is equal to str2"); }else { System.out.println("str1 is less than str2"); } } }Outputstr1 is less than str2

When you store a String asString str1 = "Hello";directly, then JVM creates a String object with the given value in a separate block of memory known as String constant pool.And whenever we try to create another String asString str2 = "Hello";JVM verifies whether any String object with the same value exists in the String constant pool, if so, instead of creating a new object JVM assigns the reference of the existing object to the new variable.And when we store String asString str = new String("Hello");using the new keyword, a new object with the given value is created irrespective of the ...

The compareTo() method of the String class. This method compares two Strings lexicographically. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by this String object is compared lexicographically to the character sequence represented by the argument string. This method returnsa negative integer if current String object lexicographically precedes the argument string.a positive integer if current String object lexicographically follows the argumenttrue when the strings are equal.ExampleLive Demoimport java.lang.*; public class StringDemo { public static void main(String[] args) { String str1 = "tutorials", str2 = "point"; ...

Strings, which are widely used in Java programming, are a sequence of characters. In Java programming language, strings are treated as objects. The Java platform provides the String class to create and manipulate strings. You can also create a String directly as − String greeting = "Hello world!"; A string literal should be enclosed in double quotes. Whenever it encounters a string literal in your code, the compiler creates a String object with its value in this case, "Hello world!'. Example Live Demo public class StringDemo { public static void main(String args[]) { ... Read More
