The equals(String str) Function
This function checks whether the string of the current string object is the same as the string str in the parameter. It
returns true, if both the strings are equal, else it returns false. This function is case-sensitive. The syntax is:

boolean <variable> = String_datatype_Variable.equals(String stringobject);
Let us see the below example:

Program 14 Write a program to compare two strings and print whether they are equal or not.

1 class equal
2 {

3 public static void main(String[] args)
4 {

5 String word1= "School";
6 String word2= "School";

7 boolean eq= word1.equals(word2);
8 if(eq)

9 System.out.println(word1 + " and " + word2 + " are equal");
10 else

11 System.out.println(word1 + " is not same as " + word2);
12 }
13 }

The output of the preceding program is as follows:
