First of all, self-learning Java is a very flexible and free way of learning. There are a large number of online courses, tutorials and programming practice platforms to choose from, and college students can select and study according to their own interests and learning progress. In addition, self-learning Java is also a way to challenge yourself. Through your own efforts and exploration, you will gradually master Java programming skills and have a great sense of accomplishment. But self-study needs strong self-discipline and self-management ability, needs to find and solve problems by yourself, and needs enough patience and perseverance when encountering learning problems.
In contrast, participating in Java training classes can provide more systematic teaching and professional teacher guidance, and you can also learn and communicate with other students to form a good learning atmosphere. At the same time, training courses usually provide some practical opportunities to help students apply what they have learned to practical projects. This is a good choice for those students who lack self-study experience or want to learn faster and improve their skills. However, it is necessary to pay a certain tuition fee and study according to the established teaching progress, which may limit students' freedom and innovation.
From my personal experience, I think both self-study and attending training courses have their own advantages, and the specific choice depends on the actual situation of the individual. During my college years, I chose to teach myself Java programming, learn the basic knowledge of Java through online courses and tutorials, and practice and apply what I have learned in practical projects. In this way, I have mastered Java programming skills, and cultivated the ability of self-solving problems and the habit of continuous learning. However, in the process of self-study, there are also some problems and puzzles, which need to spend a lot of time and energy to solve.
Later, I also attended some Java training courses. Through systematic study and practice, I further improved my programming level, made some interesting friends and broadened my social circle.
So I suggest that college students can weigh their learning styles according to their actual situation. If you have enough self-discipline and autonomous learning ability, you can choose self-study; If you need a structured learning environment and professional teacher guidance, you can choose to attend training courses. But no matter which way you choose, you need to study and practice hard, and it takes time to really master Java programming skills.
