String methods – trim() and length()

I this post, we will discuss about the string methods – trim() and length().

Let’s understand them one by one with examples.

trim():

The method trim() is used to remove leading and trailing white spaces from the input String.

e.g. Suppose, If we have a string ”   Name  “.  After using trim , String will remove the whitespaces i.e.  “Name”.

public class ExampTrim {
	public static void main(String[] args) {

		String val1 = "     How are you?  ";
		System.out.println("After trimming the string - "+val1.trim() +"??");
	}
}

length():

It is used to find out the no. of character in the string ,that is nothing but the length of the string.

public class ExampTrim {
	public static void main(String[] args) {

		String val1 = "Hello World";
		System.out.println("The length of the string is - "+val1.length());
	}
}
