Starting with JDK 8, we can use theString.join()method to represent multiline strings. The best part of thejoin()method is that it takes as the first argument a delimiter, and it uses this delimiter between the strings that will be concatenated. Stringcontent=String.join(NEW_LINE,"Line 1...
For starters, this feature simplifies string creation – you no longer need to use concatenation operators (like ‘+’), especially when working with longer or multi-line strings. In the example above, the multiline string includes a combination of String literals and variable values (via variab...
Prior to Java 13, you’d either use String concatenation or a StringBuilder in order to create a multiline String.Starting with Java 13, you can use Text Blocks, and, you don’t even have to manually transform the legacy multiline String concatenation to the new multiline text block ...

With the release of Java 8, Java has finally added support for "lambda functions", that is, variables that contain a function which can operate on data just as class methods can (well, not just as ...
You can use a custom EL resolver to alter the way variables are resolved. For instance, you can provide an EL resolver that intercepts objects with the name customer, so that ${customer} returns a value in the EL resolver instead.To reference an enum constant with an expression, use a ...
The simplicity of Pattern Matching might be deceptive. Here’s an example of how developers usually override theequals()method for a class, in this case,Monitor, with two instance variables –model(String value) andprice(double value):
In this mode, whitespace is ignored, and embedded comments starting with#are ignored until the end of a line. Comments mode can also be enabled via the embedded flag expression(?x). See Also: Constant Field Values MULTILINE public static final int MULTILINE ...
For example, a simple BASIC program to perform the direct-mode calculation from the last example could be a single line: Sign in to download full-size image Or, it could be more generalized, with multiple lines: Sign in to download full-size image Here, using the variables A, B, and ...
