java代码程序if elseif else生成流程图

以下是Java中if elseif else语句的示例代码和流程图：

int score = (int) (Math.random() * 100); // 生成0~100的随机整数
if (score >= 85) {
    System.out.println("等级A");
} else if (score >= 70) {
    System.out.println("等级B");
} else if (score >= 60) {
    System.out.println("等级C");
} else {
    System.out.println("等级D");
}

流程图如下所示：

+-------+         true          +--------+
| score |---------------------->| 等级A  |
+-------+                        +--------+
   |                                 |
   | false                           |
   |                                 |
   v                                 v
+-------+         true          +--------+
| score |---------------------->| 等级B  |
+-------+                        +--------+
   |                                 |
   | false                           |
   |                                 |
   v                                 v
+-------+         true          +--------+
| score |---------------------->| 等级C  |
+-------+                        +--------+
   |                                 |
   | false                           |
   |                                 |
   v                                 v
+-------+         true          +--------+
| score |---------------------->| 等级D  |
+-------+                        +--------+
