以下实例演示了如何在 java 中找到重复的元素：
Main.java 文件
public class MainClass {
public static void main(String[] args)
{
int[] my_array = {1, 2, 5, 5, 6, 6, 7, 2, 9, 2};
findDupicateInArray(my_array);
}
public static void findDupicateInArray(int[] a) {
int count=0;
for(int j=0;j<a.length;j++) {
for(int k =j+1;k<a.length;k++) {
if(a[j]==a[k]) {
count++;
}
}
if(count==1)
System.out.println( "重复元素 : " + a[j] );
count = 0;
}
}
}
以上代码运行输出结果为：
重复元素 : 5 重复元素 : 6 重复元素 : 2
