String endsWith()

Examples 

Let us see a few examples to demonstrate the working of the string endsWith() method.

Example 1

Code:

class Ninja1 {
    public static void main(String args[])
    {
        String str = "HelloWorld";
        boolean var1 = str.endsWith("World");
        System.out.println(var1);
    }
}

Output:

True

Explanation:

In the first example, we check whether the given string str ends with “World”. Since str contains the required sequence of characters, hence the result is true, stored in boolean variable var1.

Example 2

Code:

class Ninja2 {
    public static void main(String args[])
    {
        String str = "HelloWorld";
        boolean var2 = str.endsWith("Everyone");
        System.out.println(var2);
    }
}

Output:

False

Explanation:

In the second example, we check whether the given string str ends with “Everyone”. Since str does not contain the required sequence of characters, hence the result is false, stored in boolean variable var2.

Example 3

Code:

class Ninja3 {
    public static void main(String args[])
    {
        String str = "HelloWorld"; 
        boolean var3 = str.endsWith("");
        System.out.println(var3);
    }
}

Output:

True

Explanation:

In the third example, we check whether the given string str ends with “”. Since every string ends with “”, hence the result is true, stored in the boolean variable var3.

Example 4

Code:

class Ninja4{    
public static void main(String args[])   
  { 
   	String str = "HelloWorld";  
   	boolean var4 = string.endsWith(“helloWorld”);
   	System.out.println(var4);
  }
}  

Output:

False

Explanation

In the fourth example, we check whether the given string str ends with “helloworld”. Since h and H are not the same, hence the result is false, stored in the boolean variable var4.

Example 5

Code:

class Ninja5{   
	public static void main(String args[])  
	{  
		String str = "HelloWorld";  
		if(str.endsWith(null))  
		{  
			System.out.println("Inside the if block");  
		}  
		else  
		{  
			System.out.println("Inside the else block");  
		}  
	}  
}  

Output:

Exception in thread "main" java.lang.NullPointerException
at java.base/java.lang.String.endsWith(String.java:1485)
at EndsWithExample5.main(EndsWithExample5.java:9)

Explanation:

In the fifth example, we check whether the given string str ends with null. The output gives a null pointer exception as given in the above section.

Frequently Asked Questions

What does endsWith() do in Java?

The endsWith() method checks whether a string ends with the specified character(s).

How do you know if a string ends with certain characters?

prototype.endsWith() method determines whether a string ends with the characters of a specified string, returning true or false as appropriate.

How can you check whether a string starts with a certain character?

We can use the startsWith() method to check whether a string starts with the specified characters.
