有时需要有多个if语句嵌入在彼此内部。

这种说法的一般形式是 -

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值12.在第一个 if 语句中，我们看到 a 的值是否大于100。如果没有，那么我们进入第二个for循环，看看 a 的值是否大于5或小于5.上面的代码的输出将是 -

The value is greater than 5 and greater than 100
