Java 基本資料型別最大值極限和最小值極限,寫個小程式就很容易知道。
測試Integer, Long, Float 和Double 的最大值和最小值,程式碼如下:
public static void main(String[] args)
{
UEUE Integer.MIN_VALUE);
System.out.println("Integer.MAX_VALUE = " + Integer.MAX_VALUE);
System.out.println ("Long.MAX_VALUE = " + Long.MAX_VALUE);
System.out.println("Float.MIN_VALUE = " + Float.MIN_VALUE);
);
System.out.println("Float.MAX_VALUE = " + Float.MAX_VALUE);
System.out.println .MIN_VALUE = " + Double.MIN_VALUE);
}
輸出結果如下:
Integer.MIN_VALUE = -2147483648 (10位元)UE = -2147483648 (10位元) 223372036854775808 (19位)
Long. MAX_VALUE = 9223372036854775807
Float.MIN_VALUE = 1.4E-45
Float.MIN_NORMAL = 1.17549435E-38 🟎Float. .7976931348623157E308
Double.MIN_VALUE = 4.9E-324
