"Java" Tij demo Java Main method gets parameters from the command line __java

As we all know, Java programs can receive parameters from the command line, and the following program demonstrates how to get command-line arguments:

The code is as follows:

* * Demo Main method receive string from console
*thinking in Java Test 2.10
* @author: Wolfofsiberian/Public
class Tij_ test2_10{public
	static void Main (String args[]) {
		//Determine whether the console passes in the parameter
		if (0!= args.length) {for
			(int i=0;i <args.length;i++) {
				System.out.println ("args[" +i+ "]="));
			}
		else{
			System.out.println ("Command line is empty!");}}	

Execution Results:

(See from the execution result, when the command line passes in the parameter, use the space match to divide each parameter, and then save each parameter into a string array)
