Types of Output in Java Programming, Value bases Result in Java, Boolean Result in Java, Constant based Result in Java, and Dynamic Result in Java.
Java Input and Output Operations
- Read user input
- Read data from files
- Write program output on the console
- Write data or output in files
Types of Output/Result in Java
The Output of Computer Programming (not only in Java) basically four types,
1) Value-based Result (Fixed)
2) Boolean / Logical Result (true/false)
3) Constant based Result
4) Dynamic Result
1. Value-based Result (Fixed)
Arithmetic Operators and some predefined methods return this type of Value-based Result.
Example:
System.out.println(10+3);//13
System.out.println(5*6); //30
System.out.println(Math.max(10, 7));//10
2. Boolean / Logical Result (true/false)
Relational / Comparison Operators return Boolean Results, and some predefined methods return this type of Result
Example:
System.out.println(100<99);//false
System.out.println(100>99);//true
System.out.println(“ABC”.equals(“abc”));//false
System.out.println(“JAVA”.equals(“JAVA”));//true
3. Constant based Result (Output)
Java Returns Constant based Result in 3-way comparison of Numbers
Result Criteria,
i) if number1 < number2 then -1
ii) if number1 = number2 then 0
iii) if number1 > number2 then 1
———-
Example:
int a=7;
Integer x=a;
System.out.println(x.compareTo(9));//-1
System.out.println(x.compareTo(7));//0
System.out.println(x.compareTo(4));//1
4. Dynamic Results (Output)
i) Generating Random Numbers…
ii) Returning system Date….
———————
Example:
//Generate Random Number
System.out.println(Math.random());
//Return System date
Date date = new Date();
System.out.println(date);
