The concatenation can be done using the "+" operator. The output of this concatenation would be a String.
Ex:
public String concatenate(int val, String phrase) {
return val + phrase;
}
If you invoke this method with 10 and years as the arguments the ouput would be
10 years.
use "\n" between the words where you want a new line
"+" is the concatenation operator in Java. It can be used to concatenate two strings. Ex: String firstName = "John"; String lastName = "Morrison"; System.out.println(firstName + " " + lastName); The above code snippet would display John Morrison in the console.
Since the question is in the Java category: in Java, the method is called toString(). This method will automatically be invoked if you implicitly convert an object to String type, for example: "The answer is: " + myObject In this example, the String concatenation (the plus sign) forces the object, myObject, to type String - to do this, the object's toString() method will be called.
String.valueOf(number);

Java does not support object overriding. It does support operator overloading by means of the "+" symbol which is used for both numeric addition as well as string concatenation.

That may happen when Java tries to parse a String, to convert it into a number. In this case, if the String doesn't contain a valid number - or perhaps if it contains additional symbols not appropriate for a number - you may get this error.
One way to do this is to convert the number to a String, then use the corresponding String method to find out the length of the String.
In the context of string operations, being closed under concatenation means that when you combine two strings together, the result is still a valid string. This property is important because it ensures that string operations can be performed without creating invalid or unexpected results.
There are lots of examples of string formatting in Java. It can be difficult at times. Some of these examples are, but are not limited to; align, string, format, and JAVA.
All of the Java number classes have a parse[type] method, like parseInt() in Integer or parseDouble() in Double that convert Strings to primitive numbers. String s = getInput(); int var = Integer.parseInt(s);
".length()". The . length method is inherited from the String class.
