Initially named Oak, Java was intended for interactive television, but developers soon realised it was particularly suited for internet-based applications. By 1995, Java was officially released and became synonymous with &#8220;<strong>Write Once, Run Anywhere<\/strong>&#8220;, a philosophy that allowed developers to develop applications across multiple platforms without modifying the code again. <strong>Oracle Corporation<\/strong> maintains Java, releases new versions, and continues to grow the language.<\/p>\n<p>\ud83d\udc49 Fun fact: James Gosling is also popularly referred to as &#8220;<strong>The Father of Java<\/strong>.&#8221;<\/p>\n<h2><strong>Java Language Basics Every Beginner Should Know<\/strong><\/h2>\n<figure id=\"attachment_10946\" aria-describedby=\"caption-attachment-10946\" style=\"width: 659px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-10946\" src=\"https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/09\/Java-Language-Basics.webp\" alt=\"java language\" width=\"659\" height=\"361\" srcset=\"https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/09\/Java-Language-Basics.webp 697w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/09\/Java-Language-Basics-300x164.webp 300w, https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/09\/Java-Language-Basics-380x208.webp 380w\" sizes=\"(max-width: 659px) 100vw, 659px\" \/><figcaption id=\"caption-attachment-10946\" class=\"wp-caption-text\">Java Language Basics<\/figcaption><\/figure>\n<p>If you&#8217;re new to programming, the first step on the right path to success is having a good grasp of the basics of the Java language.
