How to highlight code in blogger or blogspot.com?

<pre class="prettyprint"><code class="language-html">YOUR CODE HRER</code></pre>

Above the code is for HTML. If you want to use syntax highlighter for specific style or language, you must replace language-HTML with language-value. Given the value and attribute of some style or language:

Highlight For	value	Attribute
HTML	html	language-html
CSS	csh	language-
JavaScript	js	language-js
XML	xml	language-xml
xHTML	xhtml	language-xhtml
C	c	language-c
C++	cpp	language-cpp
C#	cs	language-cs
PHP	php	Language-php
Python	py	language-py
Java	java	language-java
Ruby	rb	language-rb
Perl	perl	language-perl

How to optimize if condition in groovy

Main Code:

        if (text != null) {
            return text.toString().replaceAll("<[Bb][Rr]>", "\n")
        } else {
            return text
        }

Optimization#1:

return text?text.toString().replaceAll("<[Bb][Rr]>", "\n"):text

Optimization#2:

return text?toString().replaceAll("<[Bb][Rr]>", "\n")

It will give null pointer exception. because text?.toString() also gives null. But it is not checked. So do it like below:

return text?toString()?.replaceAll("<[Bb][Rr]>", "\n")

Test Case:

@Unroll
    def "#caseNo : check replaceBrTagToNewLine method"() {
        when:
        def result = itemScreenService.replaceBrTagToNewLine(text)

        then:
        assert result == expected

        where:
        caseNo | text               | expected
        1      | null               | null
        2      | ""                 | ""
        3      | "test"             | "test"
        4      | "
"             | "\n"
        5      | "test
line"     | "test\nline"
        6      | "test
line"     | "test\nline"
        7      | "test
line"     | "test\nline"
        8      | "test
line"     | "test\nline"
        9      | "



" | "\n\n\n\n"
    }
