In Java, if statement is used for testing the conditions. The condition matches the statement it returns true else it returns false. There are four types of If statement they are: 在Java中,if语句用于测试条件。 条件与返回true的语句匹配,否则返回false。 有四种类型的If语句: For example, if we...
Java if-else语句也用于测试条件。如果if条件为真(true)它执行if块中的代码,否则执行else块中的代码。语法:if(condition){ //code if condition is true }else{ //code if condition is false } Java 执行流程如下图所示 -示例代码:public class IfElseExample { public static void main(String[] args) ...
5. Using Ternary Operator to Replace Simpleif-else We can also use theternary operatorinstead of a simpleif-elsestatement to make the code more concise and readable. Consider a simpleif-elsestatement that checks if a number is greater than or less than a value, and stores the value in a...
switch是跳转表,但本质上switch和if-else两者功能可以互换,当然你非要说可以互相替换,while都可以加入...
Code that’s hard to understand is hard to maintain. Code that’s hard to maintain is next to useless. 也强调了"easy understand"代码的重要性。 写这篇文章的契机是在研读Apache ShenYu项目时,看到了很大一坨的if else语句,如下: 这里并非评论这段代码写法有问题,因为我还并没有深入到项目细节之中,可...
public final class MyClass {//Noncompliant Code Example private static String foo_bar; } class MyClass {//Compliant Solution private static String fooBar; }8."switch" statements should have at least 3 "case" clauses 当有3种或3种情况以上的时候,才用switch,否则用if/else ...
Every time a case falls through (doesn't include abreakstatement), add a comment where thebreakstatement would normally be. This is shown in the preceding code example with the/* falls through */comment. Everyswitchstatement should include a default case. Thebreakin the default case is redunda...
