Java String endsWith() with Examples

Java String.endsWith() is used to check the suffix of a given string. It verifies if the given string ends with the argument string or not. To check if a string starts with a specified substring, use startsWith() method.

Note that using the regular expression is also an effective way to check if the given string ends with the specified pattern.

The endsWith() method takes one string argument and checks if the argument string is present at the end of this string.

public boolean endsWith(String suffix);

The method returns a boolean value indicating:

• true – the string ends with the specified character(s)
• false – the string does not end with the specified character(s)

String endsWith() does not accept the regular expression as the method argument. If we pass the regex pattern as the argument, it will only be treated as a normal string.

Assertions.assertFalse( name.endsWith("java$") );

The null is not allowed as a method argument, and any such attempt will throw NullPointerException.

Assertions.assertThrows(NullPointerException.class, ()->{
    name.endsWith(null);
});
