In this section, you will learn how to compare two strings in java. The java lang package provides a method to compare two with their case either upper and lower. The equals() method provides the facility of comparing the two strings. The following program uses the equals() method and helps you to compare the two strings. If both strings are equal, it will display a message "The given strings are equal" otherwise it will show "The given string are not equal".
Description of code:
equals():
This is the method that compares an object values and returns Boolean type
value either 'true' or 'false'. If it returns 'true' for the both
objects, it will be equal otherwise not.
Here is the code of program:
import java.lang.*;
|
Output of program:
Both are equals:
| C:\vinod\Math_package>javac CompString.java C:\vinod\Math_package>java CompString String equals or not example! Please enter first string: Rose Please enter second string: Rose The given string is equals |
Both are not equals:
| C:\vinod\Math_package>java CompString String equals or not example! Please enter first string: Rose Please enter second string: rose The given string is not equals |
