You can always use String.format(....). i.e.,
String string = String.format("A String %s %2d", aStringVar, anIntVar);
I'm not sure if that is attractive enough for you, but it can be quite handy. The syntax is the same as for printf and java.util.Formatter. I've used it much especially if I want to show tabular numeric data.

This is called string interpolation; it doesn't exist as such in Java.
One approach is to use String.format:
String string = String.format("A string %s", aVariable);
Another approach is to use a templating library such as Velocity or FreeMarker.
Difference between creating a string object vs a string variable in java ?
A string variable either stores the special value null, or a reference to a string object. Multiple string variables can refer to the same string object. String literals like "hello" end up in the constant pool. All occurrences of "hello" evaluate to the same string reference. More on reddit.com

String interpolation is a straightforward and precise way to inject variable values into a string. It allows users to embed variable references directly in processed string literals.

Java Strings - How to Declare String in Java With Examples
February 13, 2025 - ( Corrections are in bold letters) By new keyword : Java String is created by using a keyword “new”. For example: String s=new String(“Welcome”); It creates two objects ( in String pool and in heap) and one reference variable where the variable ‘s’ will refer to the object in the heap.

int, float, char etc are primitive types, whereas String is a java class. Classes start with capital letters
for a list of primitive types, consult the Java documentation on primitives (http://docs.oracle.com/javase/tutorial/java/nutsandbolts/datatypes.html)
for a rundown of primitive types vs classes see this article (http://www.programmerinterview.com/index.php/java-questions/difference-between-a-primitive-type-and-a-class-type/)

It says that int,bool, char are primitive variables while String is class variable.
primitive variables are simple and have a max size so they can be easily stored/handled.
Whereas Class variables have the possibility of being complex and massive.
This potentially effects memory usage where things are stored etc so I should think of String as just a kind of
special variable type and put a big S there without moaning.

Whenever it encounters a string literal in your code, the compiler creates a String object with its valuein 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 thirteen constructors that allow you to provide the initial value of the string using different sources, such as an array of characters:

String s= "Hello";
s="Hi";
It prints Hi , How that is possible ,I am confused here . Strings are immutable means we cannot change alter the value stored in it . if we change the value then , a new string object will be created with a new memory location
String b=s.replace("Hello","Hey"); This method replaces the string value and stores in new memory location by creating new string object called b .How reassigning of strings are possible ? if Strings are immutable
Top answer 1 of 3

The s variable that you declared is a reference to a value, which contains a String. The String itself will always be immutable. However, the reference can be changed, which is what you did in your example: String s = "Hello"; s = "Hi"; To make the reference itself "immutable", you need to add the final keyword: final String s = "Hello"; s = "Hi"; // Compilation error The replace method doesn't mutate the String. It creates a new instance instead, which you can check with this example: String s = "Hello"; String b = s.replace("Hello","Hey"); System.out.println(s == b);

This method replaces the string value and stores in new memory location by creating new string object called b .How reassigning of strings are possible ? You answered your own question. The value of a String cannot be changed, but you can change what a String reference is pointing to. String a = "example1"; a = "example2"; Here the value of a is not changed, it's a reference and is changed to point to a new String instance.
