What is the not equals operator (!=)?The not-equal operator: !=, is the opposite, evaluating to true if the values are not equal. == and!= are typically used with primitives like int and boolean, but not with objects like String and Color....
如果不相等,isNotEqual为true,否则为false。 4. 示例代码 下面是一个完整的示例代码,展示了如何使用equals()方法和"!="运算符来实现String类型的不等于比较。 publicclassStringNotEqualExample{publicstaticvoidmain(String[]args){Stringstr1="Hello";Stringstr2="World";// 使用equals()方法比较booleanisEqual1=...
Java Java Operator 本文展示了如何使用我们也称为不等于运算符的 != 运算符。我们也可以使用!使用equals() 方法来检查数据的不相等性。 在Java 中使用不等于运算符 使用不等于运算符的最基本方法是检查两个变量之间的相等性。 该程序有两个 int 变量,num1 和num2。这里,num1 包含值 123,而 num2 变量具有...
="or"(!a.equals(b))"and checks if the values of two operands are equal or not, in case that values are not equal then condition becomes true. After the comparison, this operator returns a boolean value(true or false). The type of each operand that we use can be anything, for ...
