Java String length

The Java string length Method is to find and return the length of the user-specified string. The length is equal to the number of Unicode units in a string. In this article, we will show how to find the length of a String with an example.

The basic syntax of the String length method is shown below.

public int length() // It will return the integer Value as Output

//In order to use in program
String_Object.length()

• String_Object: Please specify the valid Object to find its length.

Java String length method example

This method returns the length of the user-specified string. In this program, we are going to declare a few string objects and then find the count of those characters.

package StringFunctions;

public class StringLength {
	public static void main(String[] args) {
		String str = "Hello";
		int str1 = str.length();
		String str2 = "Tutorial GateWay";
		String str3 = "Free Java Tutorial at Tutorial GateWay";
		String str4 = "Java Programming Language";
		
		System.out.println("The Length of a String Str = " + str1);
		System.out.println("The Length of a String Str2 = " + str2.length());
		System.out.println("The Length of a String Str3 = " + str3.length());
		System.out.println("The Length of a String Str4 = " + str4.length());
	}
}

In this example, First, we declared the String variable and assigned a value using the first statement.

In the next statement, we used the len() string function that will find the total number of characters of the above-specified string. Here we are assigning the output to integer values because it returns an integer value.

int str1 = str.length();

Next, we declared three more strings using the following Java statements. The following System.out.println statements will find the total characters and then print the output.

TIP: The next step is to learn about the built-in string equals, format, and substring functions.
