03 Hierarchy of operators
1. [] {}

04 new operator
The new keyword used to allocate memory at runtime.
05 dot operator

​
06 System.out.print()/System.out.println()
​
The only difference between System.out.println() and System.out.print() method is that
System.out.println() throws the cursor to the next line after printing the desired result
whereas
System.out.print() method keeps the cursor on the same line.
