1. Try to find on your keyboard the specials symbols: “ [ ] { } ( ) & * ^ ~ - + _ : ; “” \ / | ”. You should be able to find these symbols quite quickly.
2. Implement the program that prints to screen “I think: “Java is easy.” ”
3. Implement the program that prints to screen the result 11+21+31
4. Read about variables
5. Implement the program that prints to screen “area of a square with a side (side) is (area)”. The side and the area should be integer variables.
6. Implement the program that prints to screen the result of addition, subtraction, multiplication and division of two numbers. The numbers and the result should be variables.
