我如何在 java 中成对打印？

Question

代码

int Y;

System.out.print("Enter num1: ");
Y = Integer.parseInt(br.readLine());

for (int X = 0; X < Y; X++){
    System.out.println(X); 
}

当前输出：

期望输出：

0 1
2 3
4 5

Answer 1

以下是在 X

满足条件后如何添加小支票和 println

    int Y=5;
    for (int X = 0; X <= Y; X++){
         System.out.print(X+" ");
        if(X%2!=0)// Add a new line only if condition met i.e on odds
            System.out.println();
    }

输出

 0 1
 2 3
 4 5

Answer 2

    int i=0;
    while(i<Y){
        String op = "" + i;
        if(i+1 < Y)
            op += " " + (i+1);
        System.out.println(op);
        i=i+2;
    }
