Options

-cs , -checksource

Compare the source code file's modification time to that of the compiled class file, and recompile if it is newer.

-classpath path

Use path as the search path for class files, overriding $CLASSPATH . path is a colon-separated list of directories.

-debug

Print a password that must be used for debugging and allow jdb to attach itself to the session. (See jdb .)

Redefine the value of prop to be val . This option may be used any number of times.

-fullversion

Print full version information.

-help

Print a usage message.

-ms size

Set the initial size of the heap to size , which is in bytes. Append k or m to specify kilobytes or megabytes, respectively. The default heap size is 4MB.

-mx size

Set the maximum size of the heap to size , which is in bytes. Append k or m to specify kilobytes or megabytes, respectively. The default maximum size is 16MB. The value must be greater than 1000 bytes and greater than or equal to the initial heap size.

-noasyncgc

Disable asynchronous garbage collection.

-noclassgc

Disable garbage collection of Java classes.

-ss size

Set the maximum stack size of C code in a Java thread. Append k or m to specify kilobytes or megabytes, respectively. The default maximum size is 128KB.

-t

java_g only. Trace the executed instructions.

-v , -verbose

Print a message to standard output each time a class file is loaded.

-verbosegc

Print a message every time the garbage collector frees memory.

-verify

Run the byte-code verifier on all code.

-verifyremote

Run the verifier on all code loaded via a classloader. This is the default when interpreting.
