Java programmers use a Java compiler and aninterpreter. They are both essential in high-level languages like Java and both play a role converting high-level code to low-level machine code. However, they work differently. A compiler scans the complete source code in one go and combines all th...
If value is a string with spaces, then enclose it in quotation marks (for example -Dfoo="foo bar"). -d32 Runs the application in a 32-bit environment. If a 32-bit environment is not installed or is not supported, then an error will be reported. By default, the application is run...
在部分的商用虚拟机(Sun HotSpot、IBM J9)中,Java 程序最初是通过解释器(Interpreter)进行解释执行的,当虚拟机发现某个方法或代码块的运行特别频繁时,就会把这些代码认定为“热点代码”(Hot Spot Code)。为了提高热点代码的执行效率,在运行时,虚拟机将会把这些代码编译成与本地平台相关的机器码,并进行各种层次的优化...
