• How to write your first Java application in Eclipse Write code with command line parameters in Eclipse Some of these may solve your problem. You can read the following carefully or in the jump source blog:
  

• First write an application in Eclipse like this:

  package; 
  public class CommandLine{ 
  	public static void main(String[]args){ 
  		System.out.println("打印命令行参数"); 
  		for(int i=0;i<args.length;i++){ 
  		System.out.println(args[i]); 
  		} 
  	} 
  }
  

  main The args argument of the tempcodeKey1 function is a command line argument that allows data to be passed while the program is running. The type of the command line argument is an array of strings( String[] ). When running through Eclipse, you need to configure the run parameters and add the command line parameter values to be passed in.

  
  
  The way to run the above program is slightly different from normal applications.
  (1) Click the start icon of the menu bar, select the option Run Configuration , then select Java Application , select the option New Configuration from the right menu, and create a new Java application run configuration named CommandLine .
  (2) Modify the configuration of CommandLine . Select the main 0 option on the Arguments TAB and enter the command line parameters there.
  (3) Click the main 1 button to run the program.
