异常类
class OvershiftException
public class OvershiftException <: Exception {
public init()
public init(message: String)
}
功能:移位运算中,当移位位数超过操作数位数时抛出的异常。
父类型:
init()
public init()
功能:创建 OvershiftException 实例。
示例:
import std.overflow.*
main(): Int64 {
try {
// 抛出OvershiftException异常
throw OvershiftException()
} catch (e: OvershiftException) {
println("Caught Exception: ${e}")
}
return 0
}
运行结果:
Caught Exception: OvershiftException
init(String)
public init(message: String)
功能:创建带有异常信息 message 的 OvershiftException 实例。
参数:
- message: String - 异常信息。
示例:
import std.overflow.*
main(): Int64 {
try {
// 抛出带消息的OvershiftException异常
throw OvershiftException("Shift count exceeds the number of bits in the operand")
} catch (e: OvershiftException) {
println("Caught OvershiftException: ${e}")
println("Exception message: ${e.message}")
}
return 0
}
运行结果:
Caught OvershiftException: OvershiftException: Shift count exceeds the number of bits in the operand
Exception message: Shift count exceeds the number of bits in the operand
class UndershiftException
public class UndershiftException <: Exception {
public init()
public init(message: String)
}
功能:移位运算中,当移位位数小于 0 时抛出的异常。
父类型:
init()
public init()
功能:创建 UndershiftException 实例。
示例:
import std.overflow.*
main(): Int64 {
try {
// 抛出UndershiftException异常
throw UndershiftException()
} catch (e: UndershiftException) {
println("Caught UndershiftException: ${e}")
}
return 0
}
运行结果:
Caught UndershiftException: UndershiftException
init(String)
public init(message: String)
功能:创建带有异常信息 message 的 UndershiftException 实例。
参数:
- message: String - 异常信息。
示例:
import std.overflow.*
main(): Int64 {
try {
// 抛出带消息的UndershiftException异常
throw UndershiftException("Shift count is negative")
} catch (e: UndershiftException) {
println("Caught UndershiftException: ${e}")
println("Exception message: ${e.message}")
}
return 0
}
运行结果:
Caught UndershiftException: UndershiftException: Shift count is negative
Exception message: Shift count is negative
