幼き少年は━ 步みを止めはしなかった |
Osanaki shounen wa - Ayumi wo tome wa shi nakatta |
This young boy - never stopped walking onward |
Just a summary of what Java has been taught in this week's PRSP lectures and tutorial.
Methods available in the Scanner class for input are:
| nextInt() | Read in an integer |
| nextDouble() | Read in a double |
| nextBoolean() | Read in a boolean |
| next() | Read in a word |
| nextLine() | Read in a whole line |
You need to create a Scanner object first before using the methods here.
- An operator performs a specified operation on its operands and returns a value.
- The operands can be a variable, a literal, or an expression.
- Java Operators can be divided into these categories: arithmetic, relational, conditional, bitwise, logical and assignment.
- Operators that require one operand are known as Unary Operators and Operators that require two operands are known as Binary Operators.
- Binary Operators
Operator Use Description + op1 + op2 Gives the sum of op1 and op2 - op1 - op2 Subtracts op2 from op1 * op1 * op2 Gives the multiplication of op1 and op2 / op1 / op2 Divides op1 by op2 % op1 % op2 Gives the remainder when op1 divides by op2 - Division in Java
int / int gives int (all decimals lost; truncated) int / double gives double (accurate) double / int gives double (accurate) double / double gives double (accurate) - Unary Operators
Operator Use Description ++ op++ Increases the value of op by 1 -- op-- Decreases the value of op by 1 - Assignment Operator
- An assignment statement is a statement to assign a value to a variable.
- The value of a variable may be changed by the following form of statements
- Variable = Expression;
- The variable Variable is assigned the value of the Expression.
- The symbol = is called assignment operator.
- Example:
- int year = 1;
- double amount = 550.0 + 25.50;
- The assignment always proceeds from right to left. That is, the value of the operand on the right is stored into the variable on the left.
- Note: the left hand side must be a variable name and not a constant or expression with operators.
- An assignment statement is a statement to assign a value to a variable.
- Special Assignment Operators
Operator Use Description += op1 += op2 op1 = op1 + op2 -= op1 -= op2 op1 = op1 - op2 *= op1 *= op2 op1 = op1 * op2 /= op1 /= op2 op1 = op1 / op2 %= op1 %= op2 op1 = op1 % op2
Lol, Naruto chapter 402 is quite good. Looks like Sasuke has got his Eternal Mangekyou Sharingan [getting his Mangekyou Sharingan from the death of someone close to him (Orochimaru), and then getting his Eternal Mangekyou Sharingan from the death of his brother (Itachi), at the same time, lol), and he is going to crush Konoha, which is exactly opposite of what his brother Itachi wants.
Sigh... No choice, Sasuke has gone too emo. So, he renames his team from "Snake" to "Eagle", and oh, guess what? There we see Madara hanging out with Sasuke and his newly-named Team Eagle. What, Madara, intending to join Eagle as well, huh? Oh well. Have fun, the five of you. At least Sasuke's new Eternal Mangekyou Sharingan looks beautiful. XD
Bleach chapter -100 confused the hell out of me. Just when will this darn flashback end?? D:
