Java String endsWith()

The Java String class endsWith() method checks if this string ends with a given suffix. It returns true if this string ends with the given suffix; else returns false.

Signature

The syntax or signature of endsWith() method is given below.

Parameter

suffix : Sequence of character

Returns

true or false

Internal implementation

public boolean endsWith(String suffix) {  
      return startsWith(suffix, value.length - suffix.value.length);  
  }  

The internal implementation shows that the endWith() method is dependent on the startsWith() method of the String class.

Java String endsWith() Method Example

FileName: EndsWithExample.java

public class EndsWithExample{
public static void main(String args[]){
String s1="java by javatpoint";
System.out.println(s1.endsWith("t"));
System.out.println(s1.endsWith("point"));
}}

Test it Now

Output:

true
true

Java String endsWith() Method Example 2

Since the endsWith() method returns a boolean value, the method can also be used in an if statement. Observe the following program.

FileName: EndsWithExample2.java

public class EndsWithExample2 {
	public static void main(String[] args) {
		String str = "Welcome to Javatpoint.com";
		System.out.println(str.endsWith("point"));
		if(str.endsWith(".com")) {
			System.out.println("String ends with .com");
		}else System.out.println("It does not end with .com");
	}
}

Output:

false
String ends with .com

Java String endsWith() Method Example 3

The endsWith() method takes care of the case sensitiveness of the characters present in a string. The following program shows the same.

FileName: EndsWithExample3.java

public class EndsWithExample3 
{  
// main method
public static void main(String argvs[]) 
{
String str = "Welcome to JavaTpoint";

// the result of the following display statement
// shows endsWith() considers the case sensitiveness of 
// the charaters of a string
System.out.println(str.endsWith("javaTpoint")); // false because J and j are different
System.out.println(str.endsWith("Javatpoint")); // false because T and t are different
System.out.println(str.endsWith("JavaTpoint")); // true because every character is same

}
}

Output:

false
false
true

Java String endsWith() Method Example 4

When an empty string is passed in the parameter of the method endsWith(), the method always returns a true value. The reason behind this is that a string never changes when we append an empty string to it. For example,

The statement

results in

str = "Ladies and Gentlemen";

Thus, we can say that any string in Java ends with an empty string (""). Observe the

FileName: EndsWithExample4.java

public class EndsWithExample4
{  
// main method
public static void main(String argvs[]) 
{
String str = "Welcome to JavaTpoint";

// prints true
System.out.println(str.endsWith(""));

// prints false as there is no white space after the string
System.out.println(str.endsWith(" "));

}
}

Output:

true
false

Java String endsWith() Method Example 5

The endsWith() method raises the NullPointerException if one passes null in the parameter of the method. The following example shows the same.

FileName: EndsWithExample5.java

public class EndsWithExample5
{
// main method
public static void main(String argvs[])
{
String str = "Welcome to JavaTpoint!";

// invoking the method endsWith with the parameter as null
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)

Java String endsWith() Method Example 6

A String literal can also call the endsWith() method. The following program shows the same.

FileName: EndsWithExample6.java

public class EndsWithExample6
{
// main method
public static void main(String argvs[])
{
// invoking the method endsWith() using the string literal
if("Welcome to JavaTpoint".endsWith(""))
{
System.out.println("Inside the if block");
}
else
{
System.out.println("Inside the else block");
}
// invoking the method endsWith() using the string literal
if("Welcome to JavaTpoint".endsWith("point"))
{
System.out.println("Inside the if block");
}
else
{
System.out.println("Inside the else block");
}
// invoking the method endsWith() using the string literal
if("Welcome to JavaTpoint".endsWith("xyz"))
{
System.out.println("Inside the if block");
}
else
{
System.out.println("Inside the else block");
}
}
}

Output:

Inside the if block
Inside the if block
Inside the else block
