算术运算符算术运算符是基本的数学运算符,用于执行加法,减法,乘法,除法,余数和幂。
范例1:
package com.app class GroovyOperatorsExample1 { static void main(args) { int a = 10 int b = 5 int c c = a + b println "Addition = " + c c = a - b println "Subtraction = " + c c = a * b println "Multiplication = " + c c = a / b println "Division = " + c c = a % b println "Remainder= " + c c = a ** b println "Power = "+c } }

输出:
groovy操作符

在Groovy中,我们还具有一些用于执行算术运算的函数,例如加号,减号,intdiv和幂。在下面给出的示例中显示了这些功能的用法。
范例2:
package com.app class GroovyOperatorsExample2 { static void main(args) { int a = 10.3 int b = 5 int c c = a.plus(b) println "plus = " + c c = a.minus(b) println "minus = " + c c = a.intdiv(b) println "intdiv = " + c c = a.power(b) println "Power = "+c } }

输出:
groovy操作符

一元运算符通常,一元运算符只需要一个运算符即可执行该操作。一元运算符用于执行诸如递增/递减,取反和取反布尔值的操作。
范例3:
package com.app class GroovyOperatorsExample3 { static void main(args) { int a = 10 int c c = +a println "Unary plus = " + c c = -a println "Unary minus = " + c} }

输出:
groovy操作符

范例4:
package com.app class GroovyOperatorsExample4 { static void main(args) { int a = 10 int c c = a++ println "Post Increment = " + c println "Value of a after Post Increment = " + a c = ++a println "Pre Increment = " + c println "Value of a after Pre Increment = " + a int b = 10 c = b-- println "Post decrement = " + c println "Value of a after Post decrement = " + b c = --b println "Pre decrement = " + c println "Value of a after Pre decrement = " + b } }

输出:
groovy操作符

分配算术运算符在常规中,分配算术运算符用于为变量分配新值。
范例5:
package com.app class GroovyOperatorsExample5 { static void main(args) { int a = 10 a+=3 println "a+=3 ------> " + a a-=3 println "a-=3 ------> " + a a*=3 println "a*=3 ------> " + a a/=3 println "a/=3 ------> " + a a%=3 println "a%=3 ------> " + a a**=3 println "a**=3 ------> " + a } }

输出:
groovy操作符

关系运算符在常规中,关系运算符用于比较两个对象,以检查它们是否相同或不同,或者一个大于,小于或等于其他对象。
范例6:
package com.app class GroovyOperatorsExample6 { static void main(args) { int a = 10 int b = 12 boolean c println "a = 10" println "b = 12" c = a == b println "Relational Operator equals [c = a == b] ----> " + c c = a != b println "Relational Operator different [c = a == b] ----> " + c c = a < b println "Relational Operator less than [c = a < b] ----> " + c c = a < = b println "Relational Operator less than equal to [c = a < = b] ----> " + c c = a > b println "Relational Operator greater than [c = a > b] ----> " + c c = a >= b println "Relational Operator greater than equal to [c = a >= b] ----> " + c} }

输出:
groovy操作符

逻辑运算符在groovy中,布尔表达式有3个逻辑运算符,这些运算符是AND(
范例7:
package com.app class GroovyOperatorsExample7 { static void main(args) { boolean c c = true & & true println "Logical AND operator = " + c c = true || false println "Logical OR operator = " + c c = !false println "Logical NOT operator = " + c} }

输出:
groovy操作符

注意:在常规情况下,与逻辑“和”相比,逻辑“不”具有更高的优先级。范例8:
package com.app class GroovyOperatorsExample8 { static void main(args) { boolean c c = (!false & & false) printlnc } }

输出:
groovy操作符

注意:在常规情况下,逻辑“和”与逻辑“或”相比具有更高的优先级。范例9:
package com.app class GroovyOperatorsExample1 { static void main(args) { boolean c c = true || true & & false printlnc } }

输出:
groovy操作符

按位运算符在常规中,按位运算符用于对二进制数字或整数位进行运算。
范例10:
package com.app class GroovyOperatorsExample10 { static void main(args) { int a = 0b00101111 println "a = 0b00101111 ----> "+a int b = 0b000010101 println "b = 0b000010101 ----> "+b println "(a & a) ----> "+(a & a) println "(a & b) ----> "+(a & b) println "(a | a) ----> "+(a | a) println "(a | a) ----> "+(a | b) int c = 0b11111111 println "c = 0b11111111" println "((a ^ a) & c) ----> "+((a ^ a) & c) println "((a ^ b) & c) ----> "+((a ^ b) & c) println "((~a) & c) ----> "+((~a) & c) } }

输出:
groovy操作符

示例11:
package com.app class GroovyOperatorsExample11 { static void main(args) { int a = 23 int b = 43 println "Converting Integer to Binary a = 23 ----> " + Integer.toBinaryString(a) println "Converting Integer to Binary b = 43 ----> " +Integer.toBinaryString(b) println "Converting binary to integer 10111 ----> a = " + Integer.parseInt("10111", 2) println "Converting binary to integer 101011 ----> b = " + Integer.parseInt("10111", 2) } }

输出:
groovy操作符

条件运算符在Groovy中,条件操作符分为以下三种:
  • 不是操作员
在常规中,使用“非”运算符来反转布尔表达式的结果。
示例12:
package com.app class GroovyOperatorsExample12 { static void main(args) { println "(!true) ----> "+(!true) println "(!'srcmini') ----> "+(!'srcmini') println "!Null ----> "+(!'') } }

输出:
groovy操作符

  • 三元运算符
在常规中,三元运算符是if / else的快捷方式
示例13:
package com.app class GroovyOperatorsExample13 { static void main(args) { String Answer String s = 'srcmini' Answer = (s!=null & & s.length()>0) ? 'Found' : 'Not found' } }

输出:
groovy操作符

  • 猫王算子
在常规情况下,猫王运算符是三元运算符的简写属性。仅当值为true时返回。
示例14:
package com.app class GroovyOperatorsExample1 { static void main(args) { String Answer String s = 'srcmini' println Answer = s ? 'Found' : 'Not Found' println Answer = s ?: 'Found' } }

【groovy操作符】输出:
