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
