startsWith(String prefix) and endsWith(String suffix) string functions in java


startsWith(String prefix): Tests if this string starts with the specified prefix.

Syntax: public boolean startsWith(String prefix).

Note: It returns true if the character sequence represented by the argument is a prefix of the character sequence represented by this string otherwise returns false. It also returns true if the argument string is empty or is equal to this String object.

endsWith(String suffix): Tests if this string ends with the specified suffix.

Syntax: public boolean endsWith(String suffix).

Note: It returns true if the character sequence represented by the argument is a suffix of the character sequence represented by this string otherwise returns false. It also returns true if the argument string is empty or is equal to this String object.

Example:

StringExample.java

/**
 * This program is used to show the use 
 * of startsWith() and endsWith() method.
 * @author codesjava
 */
class TestString{
	String str = "codesjava";
 
	/**
	 * This method is used to show the use of startsWith() method.
	 * @author codesjava
	 */
	public void startsWithTest(){
		//return true
		System.out.println(str.startsWith("codes"));
		//return false
		System.out.println(str.startsWith("a"));
	}
 
	/**
	 * This method is used to show the use of endsWith() method.
	 * @author codesjava
	 */
	public void endsWithTest(){
		//return true
		System.out.println(str.endsWith("va"));
		//return false
		System.out.println(str.endsWith("e"));
	}
}
 
public class StringExample {
	public static void main(String args[]){
		//creating TestString obj
		TestString obj = new TestString();
 
		//method call
		obj.startsWithTest();
		obj.endsWithTest();
	}
}

Output:

true
false
true
false
