Here are two different solutions for the Simple Calculator project in Java. Solution 1: Using If-Else Statements Code: importjava.util.Scanner;publicclassSimpleCalculatorIfElse{public static void main(String[]args){//Create a ScannerobjectforinputScanner scanner=new Scanner(System.in);//Input first...
String total; if (ope.equalsIgnoreCase("+")) { total1 = input1 + input2; total = Double.toString(total1); textField.setText(total); } else if (ope.equalsIgnoreCase("-")) { total1 = input1 - input2; total = Double.toString(total1); textField.setText(total); } else if (ope.e...
{ if(AE.getSource()==B1) { sum(); } else if(AE.getSource()==B2) { subt(); } else if(AE.getSource()==B3) { mult(); } else if(AE.getSource()==B4) { div(); } } public void sum() { int i=Integer.parseInt(t1.getText()); int j=Integer.parseInt(t2.getText()); int...
