In this tutorial, we shall see how to check if two Strings are equal in Java using the method String.equals(String anotherString). Also, we shall go through an example Java program to ignore the case of the characters in the string, and check if two Strings are equal. Examples 1. Che...
String contains() and indexOf() Example in Java Let's see one quick example of how to use contains() and indexOf() method of the Java String class. Here we will use them to check if String contains a particular SubString or not. In this Java program we have used String "Hello World...
It's one of thecoding best practice in Javato useequals()method to check String equality, i.e. to check if twoStringvariable contains same values or not. This method also come with another flavor calledequalsIgnoreCase(),which perform case insensitive equality check and should be used to perf...
How to Override equals() Method in Java?We override equals() method in Java to check if two objects are equal. Before overriding equals() method in Java, first let's see when two objects are considered to be equal. Two objects are considered to be equal when they are identical (contain...
Input String: “InterviewKickstart” Reversed String: “tratskciKweivretnI” Input String: “12345” Reversed String: “54321” Input String: “Hello098” Reversed String: “890olleH” Different Methods for Reversing a String in Java There are many ways to implement this; we’ll cover the follo...
s1 and s2 are equal : true As seen in the above program, the two String variables are assigned values as follows: String s1 = new String("HELLO"); String s2 = new String("HELLO"); When the s1 and s2 objects are compared with the ‘==’ operator: ...
ParametersDescription $string1 mandatory It is the first string to be compared. $string2 mandatory It is the second string to be compared. $length mandatory It is the length of the string to be compared.It returns zero if both the strings are equal. This is a case sensitive function.<?
We will go over the array elements using the for loop and use the equals() method to check if the array element is equal to the given value.String[] vowels = { "A", "I", "E", "O", "U" }; // using simple iteration over the array elements for (String s : vowels) { if ...
As you can see the Guava version is shorter and avoids superfluous helper objects. In case of equals, it even allows for short-circuiting the evaluation if an earlier Object.equal() call returns false (to be fair: commons / lang has an ObjectUtils.equals(obj1, obj2) method with identica...
Strings are equal using == operator. Strings are not equal using != operator. Strings are not equal. Let’s explain the output. The first if statement (str1 == str2) compares two string literals, and since string literals are interned in Java, both str1 and str2 refer to the same...
