    Default JVM failed to initialize

    What's up with this. Just trying to test my hands on java packages, and had this error(by java) after successful compilation:

    Error occurred during initialization of VM
    java.lang.Error: Properties init: Could not determine current working directory.
    at java.lang.System.initProperties(Native Method)
    at java.lang.System.initializeSystemClass(System.java :1119)

    Main.java
    package com.aceix.simplecalc;
     
    import com.aceix.simplecalc.inputhandler.InputHandler;
    import com.aceix.simplecalc.mathoperation.MathOperation;
     
    public class Main {
     
    	public static void main(String[] args) {
    		try {
    			System.out.println("Welcome to Aceix's simplecalc v1.0");
     
    			double num1=Double.parseDouble((InputHandler.getInput("Enter a number: ")));
    			double num2=Double.parseDouble(InputHandler.getInput("\nEnter another number: "));
    			int op=Integer.parseInt(InputHandler.getInput("1. Add\n2. Subtract\n3. Multiply\n4. Divide\nSelection: "));
    			double ans=0.0d;
     
    			switch (op) {
    			case 1:
    				ans=MathOperation.add(num1, num2);
    				break;
    			case 2:
    				ans=MathOperation.subtract(num1, num2);
    				break;
    			case 3:
    				ans=MathOperation.multiply(num1, num2);
    				break;
    			case 4:
    				ans=MathOperation.divide(num1, num2);
    				break;
     
    			default:
    				System.out.println("Invalid selection!!!");
    				break;
    			}
     
    			System.out.println("\n\n\nYou result is: "+ans);
     
    			return;
    		} catch (Exception e) {
    			e.getMessage();
    		}
    	}
     
    }

    MathOperation.java
    package com.aceix.simplecalc.mathoperation;
     
    public class MathOperation {
    	public static double add(double lhs, double rhs) {
    		return lhs+rhs;
    	}
    	public static double subtract(double lhs, double rhs) {
    		return lhs-rhs;
    	}
    	public static double multiply(double lhs, double rhs) {
    		return lhs*rhs;
    	}
    	public static double divide(double lhs, double rhs) {
    		return lhs/rhs;
    	}
    }

    InputHandler.java
    package com.aceix.simplecalc.inputhandler;
     
    public class InputHandler {
    	public static String getInput(String prompt) {
    		System.out.println(prompt);
     
    		return System.console().readLine().trim();
    	}
    }

    And please show me a suitable way to accept input from console.

    Thanks,
    Aceix.

    Default Re: JVM failed to initialize

    In your InputHandler class you are using
    System.console().readLine().trim();
    to get the input but if you are using any IDE like eclipse then this code is not going to work.

    It's better if you take Scanner class to accept input from console.

    Default Re: JVM failed to initialize

    Yeah thanks. I used BufferredReader with the InputBufferReader class, enveloping the System.in standard input stream, since I was having some trouble with the Scanner.next(); funtcion.
