Terdapat pelbagai jenis operator.
Diberikan di bawah adalah jenis operator dalam java:
Operator Aritmetik digunakan untuk melakukan beberapa operasi aritmetik.
Berikut ialah pengendali aritmetik di Jawa.
| Operator Name/ Symbol | Definition | Example |
| Addition(+) | It helps in adding two values. | A+B |
| Subtraction(-) | It helps in subtracting two values. | A-B |
| Modulus(%) | It helps in getting the remainder obtained by dividing two values. | A%B |
| Multiplication( * ) | It helps in multiplying two values. | A*B |
| Division ( / ) | Helps in dividing two values. | A/B |
Pengendali bitwise biasanya digunakan dalam melaksanakan operasi anjakan bit dan bitwise dalam Java.
Di bawah ialah pengendali Bitwise yang biasa digunakan.
| Operator Name/ Symbol | Definition | Example |
| Bitwise AND operator (&) | It helps in comparing 2 operand’s corresponding bits. 1 will be returned if both the bits are 1; else 0 will be returned. | A&B |
| Bitwise OR operator (|) | It helps in comparing 2 operand’s corresponding bits. 1 will be returned if one of the bit is 1; else 0 will be returned. | A|B |
| Bitwise XOR operator (^) | It helps in comparing 2 operand’s corresponding bits. 1 will be returned if the corresponding bits are dissimilar, else 0 will be returned. | A^B |
| Bitwise complement operator (~) | It helps in inverting the pattern of bits. That is, 1 will be changed to 0 and 0 will be changed to 1. | ~B |
Operator Tugasan digunakan untuk memberikan nilai kepada pembolehubah tertentu.
Berikut ialah pengendali tugasan di Jawa.
| Operator Name/ Symbol | Definition | Example |
| -= | It helps subtract the right and left operators, thereby assigning the obtained result to the operator on the left. | A-=B |
| /= | Helps in dividing the right and left operators and thereby assigning the obtained result to the operator in the left. | A/=B |
| *= | It helps multiply right and left operators and thereby assign the obtained result to the operator on the left. | A*=B |
| += | It helps add right and left operators and thereby assign the obtained result to the operator on the left. | A+=B |
| ^= | Left operand value will be raised to the right operator power. | A^=B |
| %= | A modulus operator will be applied. | A%=B |
Di Java, pengendali Ternary digunakan terutamanya untuk penggantian keadaan if-then-else. Ia ialah pernyataan satu baris yang digunakan secara meluas dalam pengaturcaraan Java, yang hanya memerlukan 3 operan.
| Operator Name/ Symbol | Definition | Example |
| condition?v1: v2 | V1 will be returned if the condition mentioned is true, and v2 will be returned if the condition is false. | A>B?A:B |
Pengendali Auto Increment dan Auto Decrement di Java membantu dalam menambah dan mengurangkan nilai sebanyak 1, masing-masing.
| Operator Name/ Symbol | Definition | Example |
| ++ | The value will be incremented by 1. | A++; It is similar to A+=1 |
| — | The value will be decremented by 1. | A–; It is similar to A-=1 |
Pengendali perhubungan ialah pengendali yang membantu dalam menyemak kesamaan operan. Selain itu, operator ini juga digunakan untuk membandingkan 2 atau lebih nilai.
| Operator Name/ Symbol | Definition | Example |
| equals to(==) | If the left operand is equal to the right operand, true will be returned; else, false. | A==B |
| not equal to(!=) | If the left operand is not equal to the right operand, true will be returned; else, false. | A!=B |
| less than(<) | If the left operand is less than the right operand, true will be returned; else, false. | A |
| greater than(>) | If the left operand is greater than the right operand, true will be returned; else, false. | A>B |
| greater than or equal to(>=) | If the left operand is greater than or equal to the right operand, true will be returned else, false. | A>=B |
| Less than or equal to(<=) | If the left operand is less than or equal to the right operand, true will be returned else, false. | A<=B |
Operator Logik dalam Java biasanya digunakan dalam ungkapan Boolean.
Di bawah ialah pengendali logik dalam Java.
| Operator Name/ Symbol | Definition | Example |
| Conditional AND(&&) | If both the Boolean expressions are satisfied, true will be returned else, false. | AD |
| Conditional OR(||) | If any of the Boolean expression is satisfied, true will be returned; else, false. | AD |
| Logical NOT(!) | It helps in inverting the operand’s logical state. That is, 1 will be changed to 0 and 0 will be changed to 1. | !B |
Operator Shift dalam Java digunakan untuk mengalihkan bit ke kiri atau kanan berdasarkan keperluan.
Berikut adalah operator Shift.
| Operator Name/ Symbol | Definition | Example |
| Left Shift Operator ( << ) | X in binary notation will be shifted y bits left by shifting the zeroes from the right. | A<<2 |
| Right Shift Operator ( >> ) | X in binary notation will be shifted y bits right by discarding shifted bits. | B>>2 |
| Unsigned Right Shift Operator ( >>> ) | X in binary notation will be shifted y bits right by discarding shifted bits and shifting the zeroes from the right. | A>>>2 |
Mari kita lihat bagaimana keutamaan pengendali ini.
| Operator | Precedence |
| Postfix Operators | Exp++ Exp– |
| Unary Operators | ++Exp –Exp +_Exp –Exp~ ! |
| Multiplicative Operators | * / % |
| Additive Operators | + – |
| Shift Operators | << >> >>> |
| Relational Operators | < > <= >= instanceof |
| Equality Operators | == != |
| Bitwise AND Operator | & |
| Bitwise exclusive OR Operator | ^ |
| Bitwise inclusive OR Operator | | |
| Logical AND Operator | && |
| Logical OR Operator | || |
| Ternary Operators | ?: |
| Assignment Operators | = += -= *= /= %= &= ^= |= <<= >>= >>>= |
