In this article we will show you the solution of compare to strings in java, in Java, we can compare Strings based on their content and references.

It is employed in authentication (via the equals() method), sorting (via the compare To() procedure), reference matching (via the == operator), and so on.

In Java, there are three methods for comparing strings:

• Using the equals() Method
• Using the == Operator
• Using compareTo() method

1. Using the equals() Method

The equals() method of the String class compares the string's original content. It compares string values for equality. The String class has the following two different methods:

• This string is compared to the specified object using public boolean equals(Object another).
• equalsIgnoreCase (String each other) compares the above string to some other string while ignoring the case.

In this case, it returns a positive number if the first string has a higher lexicographic value than the second string (a difference in character value between the two strings).

If the first string has a lower lexicographic value than the second string, the function returns a negative number; if the first string has a higher lexicographic value than the second string, the function returns 0.

When we compare two strings and one of them is empty, this same function compares the length of that string. So, there could be two possibilities:

If the second string is empty, the function compares a positive integer equal to the length of the initial string.

Assume one string has uppercase letters and the other string has lowercase letters.

CompareTo() does not take the instance sensitiveness of characters into account if the result is 0; however, it does take case sensitiveness into account if the result is 1.

String objects that match and have the same case will return true if the equals() method is called.

The equalsIgnoreCase() function returns true regardless of a string's case.

When two strings are compared using the compareTo() method, a value indicating whether the first string is greater than the second string, equal to it, or less than it is returned.

Characters are collected into strings. It is not possible to modify String objects once they have been created in Java because the String class is immutable.

Step By Step Guide On Compare To Strings In Java :-

class TalkersCodeTesting{
 public static void main(String args[]){
   String s1="Amruta";
   String s2="Amruta";
   String s3=new String("Amruta");
   String s4="TalkersCode";
   System.out.println(s1.equals(s2));
   System.out.println(s1.equals(s3));
   System.out.println(s1.equals(s4));
 }
}

1. First, we must create a class called TalkersCodeTesting.
2. Next, we create a public static void main to begin the program's initialization.
3. Next, we create string objects to define values to string as s1, s2, s3.
4. Finally, we equal the objects with true and false and exit the programme.

Conclusion :-

As a result, we have successfully learned how to compare to strings in java.

A comparison is made between the original contents of the string and the values returned by the equals() method. In this function, the values of the string are compared for equality.

I hope this article on compare to strings in java helps you and the steps and method mentioned above are easy to follow and implement.
