    System.out.println( "c= "); // prompt
    double number3 = input.nextDouble();


    sum2=number1+number2+number3;
    sum = sum2/2; // add numbers
    E=Math.sqrt(sum*(sum-number1)*(sum-number2)*(sum-number3));
    System.out.println( "T=(a+b+c)/2 = "+sum ); // display sum
    System.out.println("Ε="+"\u221A"+"T*(T-a)*(T-b)*(T-c)="+"\u221A"+sum+"*("+sum+"-"+number1+")*("+sum+"-"+number2+")*("+sum+"-"+number3+")= "+E+" m^2");
