1: 2个数的最大数

package me;
public  class Me {public static void main(String[] args) {int a =10;int b = 6;int max = a>b?a:b; //方法一System.out.println(max);int max1;if (a>b){ //方法二max1 = a;System.out.println(max1);}else if (a<b){max1 = b;System.out.println(max1);}}
}

 2个数的最小数 刚好反过来

package me;
public  class Me {public static void main(String[] args) {int a =10;int b = 6;int max = a<b?a:b; //方法一System.out.println(max);int max1;if (a<b){ //方法二max1 = a;System.out.println(max1);}else if (a>b){max1 = b;System.out.println(max1);}}
}

多个数中的最大的一个数

package me;
public  class Me {public static void main(String[] args) {int [] c = {3,2,5,8,6,4,9}; //找出最大数//方法int max=0 ; //定义一个变量for(int i=0;i<c.length;i++){ //遍历数组for (int j=i-1;j>=0;j--){if (c[j+1]>c[j] && c[j+1]>max){max = c[j+1];}}}System.out.println(max);}
}
