String methods – contentEquals

ContentEquals() is used to compare the string. It has 2 types of implementations.

1. boolean contentEquals(CharSequence cs)
2. boolean contentEquals(StringBuffer sb)

Let’s understand them with the help of examples.

boolean contentEquals(CharSequence cs):

Returns true if string matches with the specified sequence of characters, else returns false.

public class StringMethodsEx {

	public static void main(String[] args) {
		
		String val1 = "Hello world!!";	
		System.out.println(val1.contentEquals("Hello world!!"));  //returns true
		System.out.println(val1.contentEquals("universe"));  //returns false	
	}
}

boolean contentEquals(StringBuffer sb):

This method compares the String with String buffer. If both matches returns true, else return false.

public class StringMethodsEx {

	public static void main(String[] args) {
		
		String val1 = "Hello world!!";	
               //String buffer
		StringBuffer sf1 = new StringBuffer("Hello world!!");
		StringBuffer sf2 = new StringBuffer("Hello universe!!");
		
		System.out.println(val1.contentEquals(sf1));  //returns true
		System.out.println(val1.contentEquals(sf2));  //returns false	
	}
}
