代码示例:Boolean类的基本用法 publicclassBooleanExample{publicstaticvoidmain(String[]args){Booleanb1=true;Booleanb2=false;// 比较两个Boolean值System.out.println("b1和b2相等吗? "+b1.equals(b2));// false// 逻辑与操作Booleanresult=Boolean.logicalAnd(b1,b2);System.out.println("b1 AND b2的结果:...
创建Boolean对象 在Java中,你可以通过多种方式创建Boolean对象。以下是一些示例: publicclassBooleanExample{publicstaticvoidmain(String[]args){// 创建Boolean对象Booleanbool1=newBoolean(true);Booleanbool2=Boolean.valueOf("true");// 输出结果System.out.println("bool1: "+bool1);System.out.println("bool2...
