如何获取此程序存储在变量中的输出？

Question

我想获取该程序的输出并将该值存储在另一个变量中，以便以后可以将其用于进一步的操作，例如当我正确运行该程序时，它要求我输入三个数字并假设我输入了5 ，6,7然后显示7是最大，然后我想将7（这是输出权！）存储在另一个变量中

这是我的代码：

import java.util.Scanner;

public class test1 {

    public void testThing(){
        System.out.println("congrats");     

    }
    public void fun() {
        int temp;
        Scanner in = new Scanner(System.in);
        temp = in.nextInt();

    }
    public void exrExr() {
        Scanner in = new Scanner(System.in);


        System.out.println("hello there!");
        int a,b,c;


        System.out.println("We'll start with a,b and c,enter their values accordingly :  ");

        a = in.nextInt();
        System.out.println("a = " + a);
        b = in.nextInt();
        System.out.println("b = " + b);
        c = in.nextInt();
        System.out.println("c = " + c);

        System.out.println("if you were wondering,among your entered numbers");

         if ( a>b && a>c ) {
             System.out.println("a is largest");
             int temp = a;
         }
         else if (b>a && b>c) {
             System.out.println("b is largest");

         }
         else if (c>a && c>b) {
             System.out.println("c is largest");

         }
         else if (a==b && a==c && b==c)
             System.out.println("all of them are same");


         test1 test1Object = new test1();
         test1Object.fun();
    }
}
