java中int转long
时间: 2023-11-18 11:03:44 浏览: 75
在Java中,将int类型转换为long类型可以使用以下方法:
1. 使用Long.parseLong()方法:先将int类型转换为字符串,然后再使用Long.parseLong()方法将字符串转换为long类型。例如:
```
int num = 18;
String str = String.valueOf(num);
long value = Long.parseLong(str);
```
2. 使用强制类型转换:将int类型的变量直接赋值给long类型的变量。例如:
```
int num = 18;
long value = (long) num;
```
需要注意的是,在进行int类型到long类型的转换时,不可以直接强制转换或获取,需要使用中间类型(int/long)进行过渡。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
