Golang is a programming language developed by Google that is statically strongly typed, compiled, concurrently typed, and has garbage collection capabilities. Int is a reserved keyword in golang. Let's take a look at the method of determining whether int is empty in golang.
Method 1:
First convert the int type data into the String type, and then determine whether the String type data is empty.
Sample code:
int point;
String val=point +"";
if("".equals(val)){
// do something...
}PS: int point is not an object, and the default is 0 when the int type is empty.
Method 2:
If point is of type int, the result obtained cannot be null.
If no field is inserted when inserting a piece of data, and the default value in the database is null, you can use
Integer point= GiftInfo.getPoints();
and then determine whether point is equal to null.
Sample code:
Integer point= GiftInfo.getPoints();
if(point == null){
// do something...

The Performance Race: Golang vs. CApr 16, 2025 am 12:07 AMGolang and C each have their own advantages in performance competitions: 1) Golang is suitable for high concurrency and rapid development, and 2) C provides higher performance and fine-grained control. The selection should be based on project requirements and team technology stack.
Golang vs. C : Code Examples and Performance AnalysisApr 15, 2025 am 12:03 AMGolang is suitable for rapid development and concurrent programming, while C is more suitable for projects that require extreme performance and underlying control. 1) Golang's concurrency model simplifies concurrency programming through goroutine and channel. 2) C's template programming provides generic code and performance optimization. 3) Golang's garbage collection is convenient but may affect performance. C's memory management is complex but the control is fine.

C and Golang: When Performance is CrucialApr 13, 2025 am 12:11 AMC is more suitable for scenarios where direct control of hardware resources and high performance optimization is required, while Golang is more suitable for scenarios where rapid development and high concurrency processing are required. 1.C's advantage lies in its close to hardware characteristics and high optimization capabilities, which are suitable for high-performance needs such as game development. 2.Golang's advantage lies in its concise syntax and natural concurrency support, which is suitable for high concurrency service development.
Golang in Action: Real-World Examples and ApplicationsApr 12, 2025 am 12:11 AMGolang excels in practical applications and is known for its simplicity, efficiency and concurrency. 1) Concurrent programming is implemented through Goroutines and Channels, 2) Flexible code is written using interfaces and polymorphisms, 3) Simplify network programming with net/http packages, 4) Build efficient concurrent crawlers, 5) Debugging and optimizing through tools and best practices.
Golang: The Go Programming Language ExplainedApr 10, 2025 am 11:18 AMThe core features of Go include garbage collection, static linking and concurrency support. 1. The concurrency model of Go language realizes efficient concurrent programming through goroutine and channel. 2. Interfaces and polymorphisms are implemented through interface methods, so that different types can be processed in a unified manner. 3. The basic usage demonstrates the efficiency of function definition and call. 4. In advanced usage, slices provide powerful functions of dynamic resizing. 5. Common errors such as race conditions can be detected and resolved through getest-race. 6. Performance optimization Reuse objects through sync.Pool to reduce garbage collection pressure.
Golang's Purpose: Building Efficient and Scalable SystemsApr 09, 2025 pm 05:17 PMGo language performs well in building efficient and scalable systems. Its advantages include: 1. High performance: compiled into machine code, fast running speed; 2. Concurrent programming: simplify multitasking through goroutines and channels; 3. Simplicity: concise syntax, reducing learning and maintenance costs; 4. Cross-platform: supports cross-platform compilation, easy deployment.
