They are identical, no conversion required.
To convert a String object to lowercase in Java, use the toLowerCase() method. "HELLO".toLowerCase() returns a new String: "hello".
The error "unclosed string literal" means that you wrote a double quote " somewhere but you didn't write another double quote later on to close the string. Note: You cannot start writing a string on one line and continue on another line, like this: System.out.println("Hello World"); If you absolutely want to distribute this over multiple lines, do it like this: System.out.println("Hello " + "World");
In JavaScript: To find the length of the string we you length method. __ __ __ Click the button to return the number of characters in the string "Hello World!". click here __ __ function myFunction() { var str = "Hello World!"; var n = str.length; document.getElementById("demo").innerHTML = n; } __ __ __ Hope this helps. Thank you
There isn't much to it:---alert("Hello " + "world!");---'alert' creates a popup, and the + does string concatenation.See related link for a Javascript tutorial.
You can use the toUpperCase() method on a String to convert any String to all uppercase.
To convert a String object to lowercase in Java, use the toLowerCase() method. "HELLO".toLowerCase() returns a new String: "hello".
There are methods in the String class; toUppercase() and toLowerCase(). i.e. String input = "Hello!"; String upper = input.toUpperCase(); //stores "HELLO!" String lower = input.toLowerCase(); //stores "hello!" -Note: these methods are NOT modifier methods therefore the original string is still "Hello!"
The plus operator between string constants allows string concatination: string a = "Hello, "; string b = "World!"; string c = a + b; The output of c would be: "Hello, World!".
public class Hello { public static void main (String args[]) { System.out.println("Hello World"); } }
The main difference is that a String is an immutable type, and a StringBuffer is designed to have its contents changed. Let's look at an example: String str = "hello"; str += " world!"; The first line of code creates a new String object with the data "hello" in it. The second line appears to simply add on some more characters to the string, but what is actually happening is that an entirely new String object is being allocated with "hello world!" as the contents. This is not ideal. For many applications, this can be good enough, but if you are modifying your strings a lot, consider using a StringBuffer instead. StringBuffer str = new StringBuffer("hello"); str.append(" world!"); This code ends up with the same result as the String example, but it doesn't need that extra step of completely recreating the String.
hello people of the world

Strings, which are widely used in Java programming, are a sequence of characters. In the Java programming language, strings are objects. The Java platform provides the String class to create and manipulate strings. Creating Strings The most direct way to create a string is to write: String greeting = "Hello world!"; In this case, "Hello world!" is a string literal-a series of characters in your code that is enclosed in double quotes. Whenever it encounters a string literal in your code, the compiler creates a String object with its value-in this case, Hello world!. As with any other object, you can create String objects by using the new keyword and a constructor. The String class has 11 constructors that allow you to provide the initial value of the string using different sources, such as an array of characters: char[] helloArray = { 'h', 'e', 'l', 'l', 'o', '.'}; String helloString = new String(helloArray); System.out.println(helloString); The last line of this code snippet displays hello. Note: The String class is immutable, so that once it is created a String object cannot be changed. The String class has a number of methods, some of which will be discussed below, that appear to modify strings. Since strings are immutable, what these methods really do is create and return a new string that contains the result of the operation.
