Interchange two value without third variable

Interchange two values without third variable

• Make new jFrame and add the components to frame like given in below figure.

• Open source code and declear three variables a,b,c as integer and also type the code of text fields.
• Type the code given below 
  
• Now I will explain how java interchanges the value:

1. Let a=10,b=20.
2. Here a=a+b means a=10+20=30.
3. Now value of a=30.
4. Then b=a-b means b=30-20=10.
5. Then a=a-b means a=30-10=20.
6. So by this java interchanges the value.

• Now print a & b.
• Run the file and see what happens.
