Sets the Java heap occupancy threshold that triggers a marking cycle. The default occupancy is forty five per cent of the whole Java heap.

In the event the argument is constructive zero or destructive zero, the result is constructive zero. If the argument is infinite, The end result is beneficial infinity. If your argument is NaN, the result is NaN.

The default worth is picked out at runtime based on method configuration. For server deployments, -Xms and -Xmx are sometimes established to a similar worth. The next illustrations demonstrate tips on how to set the utmost authorized size of allocated memory to 80 MB employing various units:

Returns the more compact of two double values. That is definitely, the result is the worth nearer to adverse infinity. If your arguments contain the exact same price, the result is that very same benefit.

If either argument is NaN, then The end result is NaN. If the initial argument is beneficial zero and the next argument is beneficial, or the 1st argument is constructive and finite and the second argument is good infinity, then the result is optimistic zero. If the 1st argument is negative zero and the next argument is positive, or the 1st argument is negative and finite and the second argument is favourable infinity, then The end result is destructive zero. If the very first argument is good zero and the 2nd argument is detrimental, or the main argument is favourable and finite and the next argument is adverse infinity, then the result is definitely the double benefit closest to pi. If the main argument is detrimental zero and the 2nd argument is destructive, or the 1st argument is negative and finite and the second argument is detrimental infinity, then The end result could be the double worth closest to -pi.

Sets the size in bytes from the code phase containing profiled solutions. This flag is utilized provided that —XX:SegmentedCodeCache is enabled.

Unlocks the choices intended for diagnosing the JVM. By default, this feature is disabled and diagnostic solutions aren’t readily available.

Allows the use of a coverage article source that restrictions the proportion of your time spent because of the JVM on GC just before an OutOfMemoryError exception is thrown.

Return d × 2scaleFactor rounded as if carried out by a single appropriately rounded floating-issue multiply into a member from the double worth set. See the Java Language Specification to get a discussion of floating-position benefit sets. When the exponent of the result is in check my blog between Double.MIN_EXPONENT and Double.MAX_EXPONENT, The solution is calculated particularly. If the exponent of The end result could well be more substantial than Double.

Windows: If the my sources choice -agentlib:foo is specified, then the JVM makes an attempt to load the library named foo.dll in The placement specified by The trail process variable.
