Groovy - 嵌套 If 语句

• 

  简述

  有时需要将多个 if 语句嵌入彼此。

  该声明的一般形式是 -

  
  if(condition) { 
     statement #1 
     statement #2 
     ... 
  } else if(condition) { 
     statement #3 
     statement #4 
  } else { 
     statement #5 
     statement #6 
  }
  

  以下是嵌套 if/else 语句的示例 -

  
  class Example { 
     static void main(String[] args) { 
        // Initializing a local variable 
        int a = 12 
            
        //Check for the boolean condition 
        if (a>100) {
           //If the condition is true print the following statement 
           println("The value is less than 100"); 
        } else 
           // Check if the value of a is greater than 5 
                 
        if (a>5) { 
           //If the condition is true print the following statement 
           println("The value is greater than 5 and greater than 100"); 
        } else { 
           //If the condition is false print the following statement 
           println("The value of a is less than 5"); 
        }  
     } 
  }         
  

  在上面的例子中，我们首先将一个变量初始化为 12。在第一个if语句中，我们查看a的值是否大于 100。如果不是，那么我们进入第二个 for 循环以查看是否a的值大于 5 或小于 5。以上代码的输出将是 -

  
  The value is greater than 5 and greater than 100
