Question

java布尔值如何转换为0 1

Answer 1

实际上java的boolean类型的值只有true和false，其不对应任何数值，无法强制转换，只能自己通过代码转换。如if(true){return 1}

Answer 2

System.out.println(p?1:0);
System.out.println(q?1:0);
System.out.println(p&q?1:0);
System.out.println(p|q?1:0);
System.out.println(!p?1:0);

Answer 3

public int convertBoolean(boolean flag){
return flag? 1: 0;
}

class LogicalOpTable{
public static void main(String args[]){
boolean p, q;
System.out.println("P\tQ\tAND\tOR\tXOR\tNOT");
p=true; q=true;
System.out.print(p + "\t" +q +"\t");
System.out.print((p&q) +"\t" + (p|q) + "\t");
System.out.println((p^q) + "\t" + (!p));
}
}如何让输出的结果显示为0和1、、

追答

public class LogicalOpTable {
public static void main(String args[]) {
boolean p, q;
System.out.println("P\tQ\tAND\tOR\tXOR\tNOT");
p = true;
q = true;
System.out.print(convertBoolean(p) + "\t" + convertBoolean(q) + "\t");
System.out.print(convertBoolean((p & q)) + "\t" + convertBoolean((p | q)) + "\t");
System.out.println(convertBoolean((p ^ q)) + "\t" + convertBoolean((!p)));
}

public static int convertBoolean(boolean flag){
return flag? 1: 0;
}
